Career: Willis started out on stage and had small parts in movies and on TV before landing a lead role in hit series Moonlighting in 1985. The show's success led to major film roles and a brief stint in music. In 1988 he scored a massive hit on the big screen with Die Hard. Other successes include Pulp Fiction, Twelve Monkeys, Armageddon, The Sixth Sense and Unbreakable. In 2001 he announced he was steering clear of violent roles, but relented and went on to star in Hostage, Sin City and 16 Blocks. He scored another major success with A Good Day to Die Hard, and always has several movies in the pipeline (a fifth Die Hard film is being developed). Other recent films include Moonrise Kingdom, Red 2 and Sin City: A Dame to Die For.

Career: Following his debut movie, The First Turn-On, in 1983, D'Onofrio became a member of the American Stanislavski Theatre Company and appeared in acclaimed productions of The Petrified Forest, Of Mice and Men, and Sexual Perversity in Chicago. His Broadway debut came in 1984's Open Admissions, and he hasn't looked back since. Films include Full Metal Jacket (for which he gained 70 pounds to play troubled Private Pyle), JFK, Malcolm X, Ed Wood, Men in Black, and The Cell. In 2001, D'Onofrio began playing Detective Robert Goren in TV series Law & Order: Criminal Intent. He quit the role in season nine, but returned in the final season of eight episodes.
