While reading the thread about spotting actors in other roles, (Hey it’s that guy!)…
Years ago I was watching “Leave it to Beaver” and there he was, Harrison Ford!
Only it wasn’t. It was Buddy Hart. Look at this guy.
Scroll down the link to see a screen shot from the show. Sheesh! Any other “I could have sworn it was…but it was actually…” moments?
I remember a few years back there was speculation that Ford was in The Great Escape (1963) as a member of the Hitler Youth:
Watching a 1962 episode of Dick van Dyke yesterday, I momentarily mistook Barry Livingston (“Ernie” on My Three Sons) for Ronnie Howard (“Opie” on Andy Griffith).
I used to confuse
with
and for years I thought
was the same guy as
No, I don’t know what’s wrong with me.
I’ve never confused this guy with another actor, but for some reason I’ve always had trouble keeping his name straight: “It’s Arthur Hill. No, wait. It’s Owen Marshall. No, wait…” 
I once got into a prolonged argument with an old girlfriend who insisted Richard Harris played Henry II in The Lion in Winter. I bet her a pepperoni pizza that it was Peter O’Toole, but we weren’t together long enough to for me to collect on it. 
This was common in the studio era, when the moguls would put near-lookalikes under contract to keep the stars from getting out of line.
An example was Nelson Eddy, who realized Jeanette MacDonald was the real draw, but he was irreplaceable as her leading man. So the brought in Alan Jones.
Eddy came back with his tail between his legs, but demanded Jones be removed. Jones went back to his dental practice, but His son carried on.
I used to get Lloyd Bridges and Donald Moffat confused. But, when looking at side-by-side photos of the two, I have no idea why.
I watched Fortitude on Amazon and I was really sure that the guy who played Vincent Rattrey also played Victor Frankenstein on Penny Dreadful. I mean, I was certain, they looked exactly alike. But scanning through Luke Treadaway’s IMDB credits didn’t show Penny Dreadful. It was so strange, because I’m really good at figuring out that this person was in x,y, and z. I’m almost never wrong.
I didn’t give it a lot of thought after that, until a couple of years later I read an article about ‘stars you didn’t know had twins’…
Yeah, turns out they’re identical twins. The one on Penny Dreadful is Harry Treadaway 
ELAINE: Andrea Doria? Isn’t that the one they did the song about?
JERRY: (Correcting her) Edmund Fitzgerald.
ELIANE: I love Edmund Fitzgerald’s voice.
JERRY: (Gives Elaine a look) No, Gordon Lightfoot was the singer. Edmund Fitzgerald was the ship.
GEORGE: (Talking about his would-be apartment) You could fit 15 people in that bathroom…
ELAINE: I think Gordon Lightfoot was the boat.
JERRY: (Sarcastic) Yeah, and it was rammed by the Cat Stevens.
I saw Victoria Tennant in a Steve Martin movie and thought she was Jessica Lange. At the time, I hadn’t seen Jessica Lange in many things, plus I’ve gotten glasses since.
I didn’t give it a lot of thought after that, until a couple of years later I read an article about ‘stars you didn’t know had twins’…
I think Penelope Cruz is one of the most beautiful women of all time. Not a twin, but her sister Monica is even more beautiful. WRT the article nobody asked ME for a donation 
I have mentioned this before on this board, and friends in real life who are old enough to remember just role their eyes at me, but…
When Tom Hanks was most famous for Bosom Buddies, and Michael Keaton was not very famous at all (he was in a show titled Working Stiffs which had a few future TV stars in the cast), I literally could not tell them apart. They were both “that fast taking, dark haired funny guy I like so much”. As time passed they grew to be very different actors – both of them to my surprise tried serious drama. I understand they both had some success in drama/thriller roles.
Just so I don’t appear as clueless as I am (or at least was), those of you who are old enough to remember when they first came out, which one was in Night Shift and which one was in Bachelor Party?
Hanks was in Bachelor Party, didn’t see Night Shift. Was Henry Winkler in the latter?
I woulda sworn the villian in Dead Calm was Ray Liotta, not Billy Zane, until a cable showing disabused me.
Yes, it was Henry Winkler’s vehicle, Keaton was only a co-star. In those days, cable was still fairly new and both of those movies were shown in fairly heavy rotation. Even though it only took three minutes to prove me wrong-- can you at least see the similarity??
I believe Keaton would have made just as good movies out of:
Bachelor Party
The Money Pit and
Dragnet as Hanks did, and further that if Hanks had stared in:
Night Shift
Mr. Mom and
Gung Ho they would have been essentially the very same movies they turned out to be with Keaton.
Early Tom Hanks movies are a little odd to watch because it’s weird to see Hanks in (say) Bachelor Party and Dragnet as the wild, irresponsible, sometimes jerkish guy, when after Big he was typecast as the everyman hero.
Well, I got the guy who played Agent Mike Weston in the television drama series The Following, confused with the guy who played Johnny Jaqobis on the Canadian television series Killjoys.
He is the identical twin brother of actor Shawn Ashmore.
Somehow I never saw it. I just remember thinking that Fonz had jumped the shark.
Agreed. I always wondered why Peter Scolari wasn’t more successful post-Bosom Buddies (Tom Hanks has had a hell of a run since then). And I think Hanks plays drama better than Keaton—Pacific Heights, Batman, and others were kind of flat for me.
Yeah. He had this appearance on Taxi which wasn’t great, but I fault the writing somewhat.
I remember mixing up Meg and Jennifer Tilly, back when they were younger. Then it was “Oh, that’s a Tilly…which one?”
When younger they looked very different, but as they continue to age, Brad Pitt and Benecio del Toro are slowly becoming the same guy.
Yes, this exactly! It was only during the early part of their careers that I confused them.
While I stand by my comments above, I think Hanks would have been a disappointing Batman and Keaton would have not done as well with Apollo 13. A League of Their Own could be well played by both actors, and Pacific Heights also, but for their early work I believe they were pretty interchangeable.
My inability to tell Ryan Gosling apart from Ryan Reynolds pre-Deadpool was almost comical.
He had one of the best moments in movie history (up until then) in that movie.
I don’t know how to spoil, but perhaps one of the powers that be will correct this for me after the fact.
The Winkler character is a really straight laced, non assertive guy who gets taken advantage of routinely. The Keaton character (and oddly enough, the love of a good woman) give him the courage to try some things outside his comfort zone. Of course things go wrong and he finds himself in jail. He is giving a pretty emotional speech about knowing he should have never gone down this path - etc., etc., etc. He says: I have fallen as far as I could have fallen." (Or something very close to that.) And Then - - - - - - -
One of the other prisoners blows him a kiss. He turns back toward his friend (or maybe the camera) and with remarkable pathos says: “I was wrong. Very, very wrong” There is something about the execution of that exchange that makes you feel sad - - - - - - and then breaks you up!
I caught an episode of Snowfall, and I said, “Hey, it’s that guy from Lost.”
But it wasn’t Matthew Fox. It was some guy named Carter Hudson who doesn’t have a Wiki page.
