Yep, Al Molina is one busy man. He was also on a TERRIBLE sitcom called Bram and Alice. With Ladies Man he was quite good - he actually made me believe he was American! (Anyone else ever notice that many British actors who do "American Accents" come out sounding like Ralph Kramden?)
As someone on IMDB put it, "Molina is one of those rare, chameleonlike performers who disappears into every part he plays." That's why it's such a shock to many people to recognize him in an earlier role. I think he was a great casting choice, at least look-wise, for Doc Ock.
