We know what you're thinking -- who on Earth is Andy Serkis, and what the freaking freak is a Gleek? Well, Gleek was basically a blue alien monkey that provided comic relief on the old-school Saturday morning cartoon version of the Justice League, The Super Friends. Andy Serkis, on the other hand, is basically Hollywood's go to guy for CGI assisted roles that require an actor with exceptional physical ability. He's played everyone from Golem in The Lord of the Rings to just about every ape in the recent Rise of the Planet of the Apes. There's a huge chance Gleek won't make it into Justice League, but if he does, then Serkis is the man!
