I think he's a good actor no question! One of my favourite films is The Basketball Diaries which Leo does some pretty amazing acting in! I've seen The Beach, which is another fave, Titanic, Catch Me If You Can, What's Eating Gilbert Grape? and I think a few other but I can't think right now!
If your gonna watch a Leo DiCaprio film, I recommend;
Basketball Diaries // The Beach // What's Eating Gilbert Grape?
Oh I love Leonardo. I think he was my first celebrity crush too haha awww. I love his acting though. He was really good in The Aviator and Catch Me If You Can. Oh and I love him in William Shakespeare's Romeo + Juliet, he's so sweet in it. His looks were at their prime then, when he was cute and young. Now he does actually look more manly, but he looked better when he was cute. He's still lovely though.
Many of his well known films are among my favourites: William Shakespeare's Romeo + Juliet, The Aviator, Titanic, Catch Me If You Can, Gangs Of New York but I haven't seen What's Eating Gilbert Grape; I really want to though. I haven't seen The Man In The Iron Mask either, would like to see that too.. especially 'cause I love period dramas. Oh and I haven't seen The Beach either.
