6. Keanu Reeves – Bram Stoker’s Dracula (1992)

Reeves has two accents that he’s capable of convincingly pulling off: surfer dude and gravelly enigma (and even these aren’t overly different form one another). Most of his roles make use of one of the two in some form or another, but for his role in Bram Stoker’s Dracula, he – for reasons unknown to us – attempted to transform his voice into that of a Victorian English gentleman.

It’s no exaggeration to say that his accent in this movie could well be considered an act of international hostility. Okay, it was more likely down to a very, very bad dialect coach, if Reeves even consulted one at all. Still, it’s Keanu, so it’s hard to be too upset about this one.

(Reeves also deserves bonus points for an AWFUL French Canadian accent in 1986 Hockey movie Youngblood, which is one of the most misguided accents ever committed to film. Luckily, it was a very small role.)
