It was quite plausible in Real Genius, mostly because the girl was just as nerdy as the guy.
Bummer!
Knocked Up is a great example. Believable premise, drunken one night stand forces two people to into a relationship after a pregnancy. Rogan’s character was a slacker and a bit selfish, but likeable and I can truly see how she would have fell for him.
Superbad, however, is another one I simply cannot buy into. Jonah Hill is not only hella unattractive, he’s a complete douche bag. No way would girl fall for that schmuck.

There is no way that I should even exist to this chick, but…

For some reason I found that I totally believed in the romance in Juno. I can imagine some people would disagree, but there was something about it that worked for me.
Oddly, I while I didn’t believe it in the movie, I could believe in it in real life. And not because he was a douche and “girls go for douches”.
I don’t think that really fits the criteria. Juno and Paulie are both misfits in their own ways, and neither is unattractive. I agree that it’s believable, but not unrealistically so.
nitpick: Zack and Miri Make a Porno
And that was the one I came in to say. Not only is their just-friends-turned-into-more relationship believable, I was astounded to find that Seth Rogan was capable of doing a really steamy, loving sex scene! I completely believed the chemistry between the two. Heck, it made **me **want to sleep with Seth Rogan, and there is no way in which he is generally attractive to me!
The people at College Humor thinks that this is mostly impossible. The only place this happens is In An Apatow World.
I also want to add that Knocked Up seemed believable to me.
Yeah, it’s amazing how she could land a hot guy like Lyle Lovett. Guess he just has bad taste in women.
Yeah, I realized that as I was boxing up the DVD to return it.
My take exactly. There was that “inner spark” between them that totally overrode the fact that he’s not my type at all. Well, he wasn’t, anyway!
You forget the way women’s minds work. I agree with you that normally that guy is a loser who has no shot with either of those girls. But remember, he got with Sarah before she was famous, so that’s at least plausible. Now, once she is hot and famous, it is simply enough that he had dated her to make him attractive to women. Something clicks in women’s minds and they think: if she dated him, then he must be desirable. It’s the David Spade effect. That guy is not slightly attractive, but once he scored Heather Locklear he was all of a sudden able to pull down all sorts of hot chicks.
I read an article about Segel in Rolling Stone - supposedly he is a huge player (and not the kind that’s only one because he has a lot of money.) Why is it so hard to believe that women would find Siegel attractive? He’s certainly more conventionally handsome than the other “leading men” in the Judd Apatow crew of actors, except for Paul Rudd I guess who is the “hot one” of the “Ap Pack.”
The article about Segel made him seem like a pretty cool guy. Good sense of humor, very confident, and charming. He’s also fairly tall, something like 6’4 and also height-weight proportional; this does generally give men an advantage with women, compared to shorter men, although not an enormous one.
I thought Forgetting Sarah Marshall was a horrible movie and I don’t think that many women would find that character that Segel played in the film to be attractive. But he is acting, after all.
Wait, this Jason Segel? How is that not, mathematically speaking, attractive? He’s adorable. I want to take him home, cook him dinner and do naughty things to him all night long.
If he played an unattractive character, then we have more a case of “Hollywood Ugly” than “Ugly Guy Gets The Hot Girl.”
I thought Jason Siegel was hotter than that other one…er, James Franco, on Freaks and Geeks. I guess in terms of personality, Franco had the brooding thing going on, but just in terms of looks, I though Siegel was cuter.
ETA: I still liked Siegel’s character better. Even though he was a bit clingy over Lindsay and couldn’t drum his way out of a paper bag. SO CUTE!
Hitch. The Kevin James character.
I loved Freaks and Geeks, but all the freaks were . . . well, freaks. Nick – Segel’s character – was the worst to me. He was way too needy, and it came off very creepy. He also looked greasy all the time.
In my opinion, Lindsay, Sam, and Bill were the only really likeable characters.
Ricky Gervais, who is plump (if not fat), but definitely nerdy and annoying, plays a misanthropic, introverted jerk of a dentist in Ghost Town and ends up having Tea Leoni fall for him. And I bought it! Great movie.
So, what have we learned? Everybody wants to fuck Seth Rogan!
Zack and Miri is another good example, it seems Seth has cornered the market on realistically do-able misfits.
I’m also in the anti-Jason Segel camp. In Forgetting Sarah Marshal it was the first relationship I found unbelievable. I didn’t see too many character traits in him that would allow me to believe that she would have dated him, even before she got famous. That being said, the second chick was a no-brainer. As someone else stated, once he’s dated a movie star…he’s got instant attractiveness. Perhaps it’s my judge of character, but I wouldn’t bet the odds on him scoring Sarah Marshal.
