DiCaprio has good chance of finally winning an Oscar, already won the Golden Globe, the Oscar is next.
Agreed, he is a very good actor and played some amazing parts lately. If someone deserves it at the moment, it is him!
I also liked mad max a lot, but I don't think it is the type of movie to win an oscar. The story is just too weak. The special effects on the other hand are amazing, as is the sound.
