Christian Bale in The Fighter. That was a performance. I know it was Mark Wahlberg's baby and wouldn't have happened without him, but Christian showed up, he said in an interview with Vibe magazine. Lets just say I grew up around people who indulged in drug addiction, and he convinced me he was on crack. Im still not sure he wasnt on crack!

The 35-year-old also rates Leonardo DiCaprios performances. 50 enjoyed the actors portrayal of aviation pioneer Howard Hughes in 2004 film The Aviator.

I like Aviator. I watched it over and over. Leonardo makes really good choices. But that was one of my favourite joints from him, he explained. (C) Cover Media
