Matthew Perry punched a hole through Jennifer Aniston’s dressing room when he found out Chris Farley died

Friends star Matthew Perry says that he punched a hole through Jennifer Aniston’s dressing room when he found out Chris Farley died.

Because the pair were both suffering from drug abuse, it made Farley's death harder to take.

Perry claims they 'barely' finished filming because of their addictions.

The film itself follows two explorers who are racing Lewis and Clark to the Pacific Ocean in 1804.

Edwards (Matthew Perry) is a glory-seeking fop who's out of his league, while Hunt (Chris Farley) is a clumsy tracker and the duo get caught up in all types of situations.

In the memoir, Perry writes: "Then, Chris Farley died.

"His disease had progressed faster than mine had. (Plus, I had a healthy fear of the word 'heroin', a fear we did not share).

"I found myself publicly discussing his death from drugs and alcohol.

"I was high the entire time.

"No one knew — not my family, my friends, no one."

Previously speaking to ABC's Diane Sawyer, Perry revealed that his addiction reached a point where his Friends co-star, Aniston, who played Rachel, had to speak to him about his addiction.

The 53-year-old recalls Aniston telling him: "'We know you're drinking'.

"Imagine how scary a moment that was. She was the one that reached out the most... I'm really grateful to her for that."

Elsewhere in the interview, the actor says: "At the time I should have been the toast of the town, I was in a dark room meeting nothing but drug dealers and completely alone.

"Secrets kill you... secrets kill people like me."

Perry also told People: "I wanted to share when I was safe from going into the dark side of everything again.

"I had to wait until I was pretty safely sober – and away from the active disease of alcoholism and addiction – to write it all down. And the main thing was, I was pretty certain that it would help people."
