Emily Blunt and Jason Segel, two increasingly big stars in Hollywood, are about to get really tiny as they gear up for Twentieth Century Fox’s Gulliver’s Travels. Blunt will play the princess of Liliput, while Segel plays Horatio, a local who befriends Black’s Lemuel Gulliver when he washes ashore on their hidden island. It’s a reunion of sorts for Segel and his Forgetting Sarah Marshall honcho Nicholas Stoller, who cowrote Gulliver’s with Joe Stillman. Rob Letterman will direct and production is set to begin in March. Black will produce through his company Electric Dynamite along with John Davis (The Express).
