Short Cuts?
He also did a fair portrayal of Pontius Pilate in The Last Temptation of Christ, as well as a few other roles.
As gooti mentioned, Collins was a child actor and went to drama school. One of his first roles was an extra in A Hard Day’s Night – he also played a crooked evangelist (I think) in an episode of Miami Vice. IMO, he needs to stick with his day job. 
I’ve seen Joe Perry of Aerosmith one time play a detective on a night time Cop show (Homicide?) and let’s just say…he’s a great guitar player
Huey Lewis played Gwyeth Paltrow’s father in that relatively recent movie about karaoke. I can’t think of the name, but the two of them sang a duet for the soundtrack called “Cruising Together” that was a big adult-contemporary hit.
David Bowie is quite a good actor, in roles like The Man Who Fell To Earth and the aforementioned Labyrinth. I agree, playing the “Goblin King” may not have been too much of a stretch for him!
Henry Rollins has had several small movie roles, the most memorable to be being in Johnny Mnemonic, a bad cyberpunk film that had a lot of potential to be cool. I always like the guy, whenever I see him in anything.
Iggy Pop also acts from time to time–I can visualize him as one of the villains in the second Crow movie, City of Angels. He pretty much plays himself.
I think Harry Connick Jr. turned out to be a very competent actor, and he’s already taken a variety of roles. He played a psycho in Copycat, a romantic lead in some Sandra Bullock chick-flick, a small part as Will Smith’s pilot buddy in Independence Day, and now he’s a regular on a sitcom.
Along these lines, I’m a huge fan of Chris Isaak, who is a natural actor and very funny and cool on The Chris Isaak Show on Showtime. I think he was also in the Twin Peaks movie, and I’d love to see him in more acting roles (as long as he doesn’t stop singing).
The Huey-Lewis-Gwyneth-Paltrow flick was “Duets” – it had another plot thread with Andre Braugher and Paul Giamatti.
It’s de rigueur at Fametracker to loath that film, but I found it watchable.
I thought Reba MacIntyre was pretty good in Tremors. Her sitcom sucks however. Not that she’s bad in it, it just sucks.
Okay, I’ll show my age… and the fact that I almost never watch TV anymore but back in the 70s I always tried to watch anything that had Dick Butkus in it. I thought he was great! ( of course I was 15 when the 70s ended)
OJ Simpson - great football player, bad actor, had some trouble with the law later on.
Joe Namath - horrible actor.
Mel Tillis has been good in broad comedy.
Dwight Yoakam has availed himself well as an actor as mentioned, then he made South Of Heaven, West Of Hell. Nobody came off good in that film.
Most of the wrestlers I’ve seen act have been lousy: Hulk Hogan, Goldberg, Diamond Dallas Page, Terry Funk, etc. Andre the Giant, already mentioned, was an exception. Roddy Piper proved to be the best of the bunch with They Live and lots of straight-to-video fare like Hell Comes To Frogtown.
Vernon Jordan was an extra for a conference scene in The Gingerbread Man with one line. IIRC, there’s a reason he’s a behind the scenes Washington insider if that’s the take they decided to use.
Good calls, all. I hadn’t heard of most of those, but had inclings those involved had done more. Surprised I hadn’t thought of the the other great model/actors but I was eating my lunch when I first posted.
Bowie was amazing in a movie called Merry Christmas Mr. Lawrence, and he wasn’t bad in The Hunger, although his acting was completely eclipsed by his makeup. He also did The Elephant Man on stage to rave reviews in the late 70s or early 80s.
Iggy Pop had a small but recurring role on a Nickelodeon show called The Adventures of Pete and Pete. I recall one episode in which Michael Stipe of REM played an ice cream man, too. Both did good jobs with their small roles.
Another mention of both Willie Nelson and Dolly Parton - while Dolly’s roles have been mainly cutesy, she does them well, and Willie is very good, IMHO.
Sting was gorgeous but trivial in both movie roles I have seen him in - Dune and The Bride (he played Dr. Frankenstein to Jennifer Beales as the monster’s bride.)
I disagree with whoever it was up there who said that Gene Simmons wasn’t any good - I loved him as the bad guy in that movie with the little spider robots… why can’t I think of the name of that one…
Cybill Shepard is another model-turned-actress. I dunno if anyone thinks she’s actually any good, but I don’t think she’s awful, at least. Wasn’t she in The Last Picture Show?
Cher - she’s been good and bad. On average I’d say she’s a fair actress.
Dennis DeYoung of Styx played Pontius Pilate in a stage version of Jesus Christ Superstar to good reviews.
I’m sure I’ll think of more.
Glenn Campbell had a co-starring role in True Grit, and he was pretty good in it.
Harry Connick, Jr. also had a good role in Memphis Belle.
Phil Collins got good reviews for his starring role in Buster.
** Randall “Tex” Cobb** plays one role well: you saw it in Rasing Arizona. He was good.
He played the same role in circa 14 other movies (like Fletch and Naked Gun), and with less support Direction and story and was less so. Still, altho he is not Sir Laurence, or even “Sir Sly” Stallone for that matter, for what he is being asked to do he is: “OK”, “acceptable”.
What disturbs me is when when CNN/FOX newsies or the McLaughlin Group appear (like in Dave, Independance Day, et al.) they are often shockingly good. it kind of shows what they might do if they wanted to fake the news
Sting was slightly better than usual in Lock, Stock, And Two Smoking Barrels as JD, Eddie’s dad. Although he just had to play “surly and pissed off” the whole time.
Oh, that reminds me - Eddie Vedder! He played Sean Penn’s younger brother in the movie Dead Man Walking.
Um. I don’t remember if he was any good, though. I just remember reading the credits and thinking, “I know I know that name…”
That would be Runaway . God, I was so in lust with Tom Selleck.
He makes a good living as an actor (aka professional wrestler) already.
You know someone’s a bad actor when he can’t even play himself well.
Michael Jordan in Space Jam.
Shaq has had a couple movie roles. Steel and Kazaam come to mind. Nothing really incredible there either.
I did surprising like Justin Timberlake on SNL. His Ashton Kutcher impression was really funny.
Say what you will about his acting, but you can’t step to his skills on the mic. SHAQ-FU, DA RETURN?!? SLAMMIN!
She sure was - it was her first film. She also had a big role in Taxi Driver. Of course, most probably know her from TV’s Moonlighting. I think she was fine in all of them, although she does seem to play slightly egotistical characters from time to time.
