Matthew Perry Doesn't Remember Filming 3 Years Of 'Friends'

The actor publicly struggled with drug and alcohol addiction while on the show.
|

You can hardly tell while watching old reruns, but Matthew Perry battled drug and alcohol addiction during his time on "Friends."

The actor told BBC Radio 2 Friday that he doesn't recall filming three years of the hit sitcom.

The actor was responding to a question about his least favourite episode.

"I think the answer is, I don't remember three years of it. So none of those ... somewhere between Season 3 and 6."

He told ABC News in 2013 that he tried to hide his addictions, but others eventually found out.

"Mostly it was drinking, you know, and opiates," he said.

The actor was in and out of rehab, and didn't look healthy — he said he hates to see paparazzi photos of himself from that time.

"I honestly recoil," he said.

He's now substance-free and has tried to use his personal fight to help others. He opened a men's sober living facility back in 2013 and has been honoured by the White House for his advocacy in favour of U.S. drug courts, which aim to rehabilitate nonviolent drug offenders instead of incarcerating them.

Now in London preparing for his play, "The End of Longing," he'll be the only member of the "Friends" cast not to be on an upcoming NBC special. However, he told The Graham Norton Show that he'll still be a part of it by introducing them from afar.

But the cast might be open to the idea of an actual reunion, he told the BBC Friday.

"It's kind of tough, because we've ended on such a high note, that we don't want to ruin it."

"I hit rock bottom when I was doing “The Brady Brides.” I was supposed to be at the studio, screen testing to pick the guy that would play my husband. At this time, I had been up for three days doing coke and was playing solitaire in my closet. My agent had to go to the sixth floor, climb into my place, tear off my clothes and get me in the shower. He said, “You have to get to Paramount right now, and you have a problem.” I couldn’t hide anymore. Everyone knew -- the producers knew, everyone at Paramount knew, the guys testing to play my husband knew. It was the first time I had to face that I really had a problem."["Today," 2008] (credit:Getty)
