Last night I watched the JACKAL for the first time. I won it as a prize for a SMASH BROS BRAWL tourny I won. Just in case anyone is unfamiliar with the film, Richard Gere plays an Irish Terrorist...and attempts an Irish accent. I say "attempts" because he fails miserably at it. Overall, this was one of the least convincing acting roles I've seen and it got me to wondering. What was the least convincing performance you have seen in a movie or TV show?
