10 Most Embarrassing Film Debuts From The Marvel Cinematic Universe Cast

Before he was Bucky Barnes, Sebastian Stan was a total douchebag in Tony 'n' Tina's Wedding. Also starring Mila Kunis, Jon Bernthal, Adrian Grenier and, rather inexplicably, New Kids on the Block's Joey McIntyre, this might be the weirdest movie to come out of 2004. And this is a year that gave us such gems as You Got Served, Napoleon Dynamite, and Super Babies: Baby Geniuses 2.

The film is actually based on an immersive theater production where the actors improv their way through an Italian-American wedding reception, treating the audience members as guests.

This, amazingly, did not make for a great film, unless of course you love watching former boy band members wing their way through dated stereotypes and filling every lapse in comedic rhythm with the f-word.

Stan gets his feet wet in these very odd waters as Johnny, a groomsman who sleepwalks through the festivities while drunk out of his mind, incoherently rambling and generally acting like a bastard. That, by the way, is the gist of the entire movie.
