Heath Ledger used to confide his problems to Verne Troyer.
The late actor - who died of an accidental drug overdose in January 2008 - bonded with his 'The Imaginarium of Doctor Parnassus' co-star over dinner and amazed the 'Austin Powers' star with revelations about his life.
Verne said: "My best memory? Having dinner with him and sitting right next to him, him just being open with his life and things like that. He was a really cool guy. And him telling me things like that, I wasn't shocked, just surprised, just the things in his life, what was going on.
"I felt honoured that he would trust me in that way. He was a very open character."
Heath was filming 'The Imaginarium of Doctor Parnassus' when he died and Verne admits his friend was missed at last night's (06.10.09) gala premiere in London's Leicester Square.
He told BANG Showbiz: "It's emotional for everybody. Heath was such an amazing person, such a giving person and we all loved him. I'm sure he is looking down and feeling honored that everybody is here to support him and our movie."
Despite his sadness, Verne - who was joined at the premiere by his co-stars Lily Cole and Paloma Faith and director Terry Gilliam - is enjoying his time in the UK and is even considering relocating to London.
He said: "Would I move here? Possibly, yeah, I'm working on a project with Lee Francis right now and we're shopping it around, so if it happens then I'll be here for a few months.
"I like British people, everyone is so nice and friendly. In Los Angeles, it's so fake and superficial, here they're not."
