Tom Selleck returned to TV on a full time basis a few years ago to headline the series Blue Bloods, which ended up being a huge hit for CBS. 

But Selleck is probably best known for his work as Magnum PI AND that classic flick, Three Men and Baby, which was directed by the recently passed Leonard Nimoy.   

He was on Late Night with Seth Meyers last night and talked about working with Nimoy in the blockbuster family flick.
