He added: ‘The second or third [word], that's fine. But the first? No. It's going to have to be mom or dad. I'm rooting for mom.’

He told E! News: ‘I've probably seen about 400 [Deadpools] at this point.I saw a couple that were awesome, that were really amazing. One guy [had] contact lenses underneath, really elaborate stuff.

‘I took a picture with about eight of them that I saw just outside a little while ago...It was cool to see that. It was cool to see that level of passion and determination to make a perfect Deadpool.’
