Hey, that man has no dick. Well, that’s what I heard!
William Atherton; I gotta see this movie.
I saw it on cable back late 80s [like 88, 89?] and actually hated it. I had been reading old Doc Savage pulps [got to love random boxes of auction stuff] and the movie was nothing like them. I can see Ron Ely as Doc, but the others sort of sucked, the plot sucked and the writing sucked.
And yes, Xanadu did have a good soundtrack as did Highlander [though I love Clancy Brown as Kurgan =)]
Outland with Sean Connery and Peter Boyle. Rip off of High Noon set in outer space. Frances Sternhagen practically steals the movie. Very nice to look at, empty headed as a mannequin. Still, I must watch when I can find it.
Looker with Albert Finney and Susan Dey. Michael Crichton nonsense about models being murdered after being digitally simulated. Not as interesting as it might sound. But, watch I must.
He was in a series of (IIRC) Volkswagen commercials that were popular at the time. His signature line was “don’t sass me, boy!”. The character was popular enough that they put him in those Bond films.
I’d watch commercials for laundry detergent if Susan Dey were in them! 
Does the musical film Evita count? I was obsessed as a teenager. I know it almost completely by heart. Very clever lyrics. I still sing them sometimes.
Such a shame she wandered
Into our enclosure
Our unfortunate disposure
Has forced us to be blunt
No, we wouldn’t mind
Seeing her at Herrod’s
But behind the jewelry counter,
Not in front!
As an adult I have never seen anyone mention this film favorably.
[I am seeing all the lyrics online say “how unfortunate this person has forced us to be blunt.” I don’t think so.]
…and Silver Streak.
So you have seen it. I think they used her doppelgänger in one of the in-movie commercials.
I second your opinion, including about Sternhagen. There really isn’t much to it, but one keeps watching.
“Take two aspirin and call me in the morning. That’s a doctor joke.” 
Harlan Ellison wrote a wonderful venomous little piece eviscerating Outland, and pointing out its manifold mistakes. Well worth reading.
The scientific liberties taken in “The Core” were outlandish, some of the acting absolutely over the top, yet I find it strangely re-watchable.
This is a weird one. Munster Go Home. Basically an extended “vacation episode” of The Munsters - but it is in color! That beautiful oversaturated color that can only be found in films and TV from around 1965-1967. Batman ‘66, pop art, swinging London, late French New Wave, comic bookish color. Munster Go Home was the beginning of my love affair with color films made within that brief window.
A lot of those B-pictures were mediocre but memorable. I’ve mentioned Vanishing Point, and you’ve mentioned Electra Glide in Blue, and we can add Two-Lane Blacktop, Chato’s Land, Duel at Diablo, They Came to Rob Las Vegas, and Fuzz. Pretty much anything by Russ Meyer (seriously, how can a film with the name Faster, Pussycat! Kill! Kill! be anything but memorable, based on the title alone?), and by Roger Corman.
All inexpensively produced, and pretty mediocre. Heck, I struggle to remember some heavily-hyped and well-acted A-pictures (Six Weeks (1982), Dudley Moore, Mary Tyler Moore; Hotel (1967), Rod Taylor; and The Hospital (1971), George C. Scott). But I, and many of us, I would imagine, can remember the cheap and mediocre B-pictures. The fact that we remember them nowadays ought to say something.
Yeah, I’m a sucker for a lot of those revisionist Westerns of the late 1960’s and 1970’s. I can probably (maybe) resist it now, but I’ve probably compulsively watched Chato’s Land and similar films like Eastwood’s High Plains Drifter a dozen times each on daytime re-runs or cable over the decades.
I’m not sure I’d rate those two as mediocre per se, though some sure are. But I wouldn’t call them high art, either.
I didn’t know that! Interesting, thanks.
Similar character, different actor. Joe Higgins as Sheriff J. W. Higgins, for Dodge.
He was in print ads, too.
I feel like there are two types of mediocre fantasy/adventure/action films. One is the type where the filmmakers are making a movie and doing their best, and it turns out “cheesy, bombastic, and absurd”. I feel like Highlander and The Final Countdown fell in that category.
The other is when they’re making a movie that they know will be “bad” in some sense, but that’s part of the point. Flash Gordon falls in that category, I feel, as does Army of Darkness. You could even argue that they’re neither mediocre nor bad; that’s part of the point for both movies, as @odesio says.
I’ve always felt like The Spy Who Loved Me is up there for kind of mediocre relative to the filmic merits of some other Bond movies, but it’s also the ultimate example of the big, bombastic, over the top Bond film in the You Only Live Twice vein. I mean it’s got a supervillain who wants to destroy the world, a huge underwater lair, a supertanker that eats nuclear missile submarines, thousands of henchmen, the first appearance of Jaws, and none of it is as clearly absurd as later movies’ villain’s plans are.
My one memory of Outland is the way the lesser gravity of its location only applied when they were outside.
Green Street R 2005 Rated 45% on Rotten Tomatoes by critics. It’s had something of a revival with audiences as that rating is now 87%, up from around 50% a decade ago. Elijah Wood is something of a post college layabout who decides to move in with his sister living in London shacked up with an ex soccer hooligan. It’s not long before the bored fish out of water Elijah begins spending time in this violent underworld with the younger brother of said ex hooligan who is still very much in the game.
I enjoyed it start to finish. It’s not over the top like The Firm (1989, not the Tom Cruise 1993 film) or any Guy Ritchie film, it’s more like a modern honest look at something unsavory akin to American History X. It’s worth seeing.
