Actors in Atypical Roles

I'm interested in dramas or movies that involve actors that we're used to seeing as good guys take on different kinds of roles. They might be crazy, killers (or both), or just something really different that made you surprised to see them in that kind of role. Some examples that come to mind are Jang Keun Suk in 'Itaewon Homicide', Nakama Yukie in 'Mr Brain', and Shirota Yu in Koshonin. Any country is fine. Thanks in advance.

shinichi in Hard Romanticker !

I'd say Nishijima Takahiro in Love Exposure. After that movie I can't see him the same way I saw him before :'DD And GACKT... well he's always weird so I'm waiting a role where he's "normal". He was pretty normal in Akumu-chan so yeah it was kinda shocking to see him play "normal" character 8DD
