Sean Penn is brilliant in All The King's Men, but the movie is ruined by bad accents from co-stars Jude Law and Kate Winslet. That said, at least they tried to sound like they were from Louisiana. Anthony Hopkins doesn't even bother to try. For us, his is the worst movie accent in film history.
The bloggas at Deputy Dog have their own list of 13 godawful accents that have rolled off the lips of alleged actors. Kevin Costner in Robin Hood. Brad Pitt in The Devil's Own. Julia Roberts in Mary Reilly. Delightfully bad, all.
Your picks? No fair targeting Tony Curtis in Spartacus. Some things are sacred.
