1. Cam Neely - Sea Bass In Dumb & Dumber
The Role: Sea Bass, the angry trucker who gets ripped off by Harry (Jeff Daniels) and Lloyd (Jim Carrey), before later revealing himself as a sexual deviant who tries to molest Lloyd in a toilet stall.
Why It's Amazing: Again, perhaps stretching the "extra" designation a little, but Neely gives a riotously funny, scary performance as the guy who gobs in Harry's burger and then later reveals his sublimated homosexual side.
What Happened?: I had no idea about this for years, but Sea Bass is actually played by a retired Canadian ice hockey player called Cam Neely. He plays Officer Sea Bass in the Farrelly's Me Myself & Irene, and also appears briefly in their movie Stuck On You. Given that his primary profession resided elsewhere, it's little surprise that we haven't seen him carving out a niche for himself as mean badasses... Which movie extras do you love the most? Are there any great ones we missed? Let us know in the comments below.
