5. Gerard Butler – P.S. I Love You (2007)

Despite his obvious Scottishness, actor Gerard Butler decided to attempt an Irish accent for his role in 2007 romantic drama, P.S. I Love You. The film is based on the book of the same name by Celia Ahern, in which Butler’s character is Irish, but it seems as though the actor may have lied about his ability to do an Irish accent in order to get the part.

The result was mostly Butler’s natural Scottish accent with notes of an Irish brogue thrown in seemingly at random. It’s a weird and uneven mixture of two very distinct accents, and it was more than a little jarring. It doesn’t help that many of his character’s lines are delivered in voiceovers, which means that there’s very little to distract from the unholy mingling of accents.

What makes it even stranger is that Butler’s Scottish accent probably would have sufficed. It could have easily been explained with a throwaway line of additional dialogue, but most international audiences probably wouldn’t even recognize the difference, anyway. Instead, Butler opted to try to sound Irish, failed spectacularly, and made every single one of his scenes vaguely uncomfortable to watch (or listen to, at least).
