Is it just us, or does Hollywood seem like a history class lately? All the hotties are working on historical biopics. Leonardo DiCaprio is leading the trend—he has two in the works with director Martin Scorcese. First up, he'll play former prez Teddy Roosevelt. And although it's not official yet, he is the frontrunner in the skirmish to play Ol' Blue Eyes, Frank Sinatra. Sometimes history can be fun.
