Colin Trevorrow is a busy man. He’s just coming off the mega-success of Jurassic World, and he’s attached to direct Star Wars Episode IX. However before then he hopes to make the much smaller, The Book Of Henry, which has just added Sarah Silverman, Lee Pace, and Dean Norris to its cast, according to TheWrap.

They join Naomi Watts and child actors Jaeden Lieberher and Jacob Tremblay. Unfortunately though the new casting doesn’t come with any more info about the plot. All we know is that Gregg Hurwitz wrote the script, which has been described as “remarkable” and “a true original.”

Between Jurassic World and Star Wars, Trevorrow also hopes to make Stealing Time, which has added Pixels Timothy Dowling as a screenwriter. The film, which has been likened to a 1980s Amblin movie, is about a man who invents a time machine but gets lost in the past. His son and grandson have to fix the device in order to rescue him.
