This November, Three Men And A Baby will celebrate its 30th anniversary.

Released in November 1987 and directed by Leonard Nimoy - yes, Spock directed Three Men And A Baby - the film became a huge success for just about everyone concerned and has remained popular to this day because, well, it's actually a cracking little comedy with enormous heart.

While we know what Tom Selleck, Ted Danson and Steve Gutenberg are up to (Blue Bloods, CSI: Cyber and Sharknado 4, respectively), whatever happened to baby Mary? Well, as it turns out, the baby in question was actually a set of identical twins - a common practice in most films when it comes to filming babies. The two were interviewed for Today back in 2014 and, well, here they are.

Lisa and Michelle Blair were four months old when the film was originally made, but neither went on to pursue a career in acting. As their mother tells it, she applied for the casting call for the two girls as she was bored at home and thought it was a small little scene in a film and not a leading role.

During filming, both babies became enamoured with the microphones dotted around the set which meant that Leonard Nimoy and the three actors had to hide them so that the babies would stop looking at them or trying to reach for them. In fact, the babies really did pee on Tom Selleck during the film and the three actors often were forced to try and change their nappies to help get them into character.

That's commitment right there, folks.
