Tomorrow evening on HBO, Will Ferrell hits fans with a comedy curveball. In Ferrell Takes the Field, the actor and comedian tries his hand at 10 different positions with 10 different MLB teams in a 24-hour stretch. And it's all for a good cause!

It's a big weekend for HBO, so let's stick with it for a moment. On Sunday, Project Greenlight and Doll & Em are both back for all-new seasons. Both offer a behind-the-scenes take on Hollywood, albeit in a very different way.

MLB on TBS continues Sunday when the Toronto Blue Jays take on the New York Yankees.

Monday, it's the premiere of the very first crime show to air in daytime syndication – Crime Watch Daily from Warner Bros. Television Group.

And round 2 of the Republican Presidential Debates airs Wednesday only on CNN.
