Robert Downey Jr. on 'Sherlock' Sequel: 'It's Better Than the First'

Robert Downey Jr., star of "Sherlock Holmes: A Game of Shadows," sat down with "Extra's" Jerry Penacoli, and said, "This is actually better than the first. I've heard that happens with sequels every once and a while."

Robert, who is going to be a father again with wife Susan Downey, revealed he knows the sex and name of his baby, but added, "[Susan] told me that I will lose my tongue if I share it before she's ready."

The actor, who might have been a bit too honest, said, "[Susan's] huge! Is she huge? Don't tell her that! Most gals say, 'Oh my God, you're barely showing.' But she's kind of a tiny person, so to me... she's expanded."

Downey, who made a speech at the American Cinematheque Awards in October, asked the public to forgive his good friend Mel Gibson. Downey, 46, told Penacoli, "I think it's always embarrassing to show someone that you're a friend and you love them, in public. So, I think he [Gibson] was probably a little surprised."

Part two of the action-packed adventure for "Sherlock Holmes" begins Dec. 16.
