Garry Shandling Was Generous with Sean Penn in Life and Death

EXCLUSIVE

Garry Shandling was so moved by Sean Penn's passion for the people of Haiti, he made sure the actor's charity got a chunk of his fortune when he died.

TMZ's obtained a copy of the late comedian's will and he's giving away some of his fortune to Penn's J/P Haitian Relief Organization. Garry was a longtime supporter of Penn's charity, attending fundraisers and making countless contributions.

Garry donated a whopping $10k just to back a Haitian runner in the NYC Marathon a couple years ago -- so you've gotta figure he left way north of that to Penn's group.

It's unclear how much he left when he died from a heart attack in March. That detail is held in Shandling's private trust.

According to the will, he also left dough for the University of California's school system -- even though he attended University of Arizona -- the Cystic Fibrosis Foundation, as well as 11 relatives.
