People are only just realizing that Jack Black's real name is not Jack Black

Jack Black is a man who most people absolutely adore... but did you know that Jack Black isn't his real name?

Jack has done a number of incredible movies, including School of Rock, Tropic Thunder, Jumanji, and Tropic Thunder.

The Tenacious D musician is often seen as one of the nice guys in Hollywood, and his carefree, hilarious antics back up that perception.

Given that he has one of the most memorable names in showbiz, it's taken some people by surprise that his birth name isn't actually Jack Black.

According to Empire Online, Jack was born in 1969 in Santi Monica, California to Judith Love Cohen & Thomas William Black.

But who are Jack's parents?

Both Judith and Thomas played pivotal roles in the aerospace sector, contributing significantly to projects like the Hubble Space Telescope.

Judith, in particular, etched her name in history when she played a crucial role in assisting Apollo 13's safe return to Earth in 1970 after an oxygen tank ruptured, per PEOPLE.

The birth name they gave their son is Thomas Jacob Black.

It turns out that not many people knew that Jack Black is not, in fact, the actor's birth name.
