Andrew Garfield plays a 17th-century Jesuit priest in Martin Scorcese's film Silence, which was released in December. For this role, he spent an entire year meditating on the idea of religion, materialism and spirituality. But he's not always serious--here, the 33-year-old actor reflects on his favorite birthday memory, which took place at Disneyland, and involved his best friends and pot brownies.

What was your favorite birthday?
My 29th birthday, weirdly. It was perfect. It was heaven. I was with my favorite people in the world, eight of my closest friends. And, um, I’m just gonna tell you this straight up. They came out to L.A. to surprise me and we went to Disneyland and we ate pot brownies. And it was literally heaven.

Did you go on the teacups?
How about Space Mountain three times in a row. I freaked out on It’s a Small World. I was like, "it is – it is a fucking small world – it’s a fucking – it’s a really fucking small world guys, is anyone else seeing how small it is?" Amazing. Amazing.

Did the song start to make you feel insane, as well?
Yeah. There was a moment where me and my friends found ourselves walking Fantasy Land, and there was a song that was playing coming out of the trees and we were all doing this dancing through and I think at one point we all started looking around going, “Why are we all doing the same dance, how did this happen?” And we had this girl called Chantelle – God bless you, Chantelle, wherever you are. I think she was that innocent and pure of heart that she had no idea that we were on drugs. She was just like, “You guys are great, I wish all of my guides were like you.” It was wild. It was one of the best days of my life. It really was.

It sounds fabulous. And did you end up crashing at the Disney Hotel or you all went home?
No, we went back to my house and just kind of talked about insane that day was, because we were all having our own experiences, and I think we all came back and were like, “Were you thinking this at...” and then we all realized we were thinking so many of the same things – stoned conversations.

Did everyone freak out on Small World?
I don’t know if everyone did. I definitely did. I think everyone had a different freak out at a different place. My friend couldn’t handle – I can’t remember what it was, but it was a really lame ride. He was like, “You know I can’t do it. I can’t do it. No, you go – I’m good. If I’m not here when you come back, be worried, because I’m probably going somewhere to do damage to myself.” It was a really intense day but we all had each others’ backs.

I think I almost bought a Chewbacca backpack, as well, I was that stoned. I thought it was a good idea to get one of those backpacks that are the shape of Chewbacca, so it’s like the back of Chewbacca’s head, and his arms are like over my shoulder and his legs are around my waist. In retrospect, I should have actually just got it. It was a great backpack. It was really cute.

I’m not a big drug user, though, I just want to say that. I use it more for like ritual purposes. I’m not like a recreational [user], I’m responsible with drugs. Any young people watching, don’t hold it lightly, because it can really be a bad thing.

It can be very bad. Just respect it, respect yourself. And check in with yourself about it. You know your limits, don’t go crazy on it. I need to say that. Because that’s a fun drug story, and Bill Hicks would be proud of me.
