While not sinking to the same depths as Richard Gere in "The Jackal," Brad Pitt still manages to embarrass himself - and indeed anyone from Northern Ireland - with his efforts at playing Frankie Gallagher, an IRA man on-the-run.
Apparently, Pitt spent a few days hanging around Belfast to perfect a Belfast accent. (He was even attacked in West Belfast while he was researching the role.)
Probably could have done with a few more days in Belfast....
9. GERARD BUTLER IN "P.S. I LOVE YOU"
Everyone involved in the making of this film, from the producer to the coffee maker, should be rounded up and shot - it's that bad.
First on the list to go is Gerard Butler, who plays lovable Irishman Gerry Kennedy, and whose Irish accent is only one of the many problems in this pretty awful film.
Sean Connery has shown that even Scottish actors can have trouble with an Irish accent - a point also demonstrated by Butler in this movie.
P.S. Gerry, your accent sucks.
10. THE LEPRECHAUN IN "LEPRECHAUN"
Like many of the films featured on this list, this movie falls into the "It's so bad, it's good" category. And it's hard not to laugh at a movie with the tagline, "Your luck just ran out."
This horror gained something of a cult following, and was also notable for giving Jennifer Aniston one of her first roles.
Of course, in a movie about Leprechauns, anything less than a ridiculous "Oirish" accent would be a total shock - and Leprechaun doesn't disappoint.
