Paramount: Monday, 6:30 p.m.
Paramount will be teasing several of its big summer movies, including Michael Bay's Transformers: Age of Extinction, which will star Mark Wahlberg. The studio will also preview the live-action/CG pic Teenage Mutant Ninja Turtles and the Brett Ratner-helmed Hercules. The presentation should feature plenty of talent, including Wahlberg of Transformers, Will Arnett for Teenage Mutant Ninja Turtles and Dwayne Johnson for Hercules. Christopher Nolan (who is participating in a panel at the convention) should make an appearance to tout his highly anticipated film Interstellar, which hits theaters in November.
We've known for a while that one of the plot points for Transformers: Age of Extinction would be humans reverse engineering Transformer tech and building their own mechs. According to the tweet Optimus Prime will take on one of these human controlled mechs known as an "Avatron".
