Casting the title characters proved difficult for the studio. Originally slated were Sean Penn to play Larry, Benicio del Toro to play Moe, and Jim Carrey to play Curly. Both Penn and del Toro left the project but returned while no official confirmation had been made about Jim Carrey. When del Toro was interviewed on MTV News for "The Wolfman", he spoke about playing Moe. He was later asked who was going to play Larry and Curly in the film and commented that he still thought that Sean Penn and Jim Carrey were going to play them, though he added, "Nothing is for sure yet."
