Ellen Page’s dance card is filling up. The “Juno” star this week signed on to star in “Peacock,” a psychological thriller, opposite Cillian Murphy (Batman Begins). The film marks the third new project Page has joined in the last two months, all for production company Mandate, the group behind “Juno.” The other two are Drew Barrymore’s directorial debut, “Whip It!,” and Sam Raimi’s horror film “Drag Me To Hell.”
