On Sunday, actor William Hurt passed away.

The Oscar winner was 71 years old.

His son said he passed away from natural causes at home.

Actor Ben Stiller took the loss especially hard.

He penned a long, touching tribute to Hurt on Twitter.

He explained that he had grown up with Hurt.

Stiller’s father worked with him on a Broadway play that ran for many years.

He explained that he talked to Stiller a lot about acting while he was growing up.

He said that Hurt inspired him and his sister to “be who we were and commit to the work.”
