The 38-year-old actor's little girl James, seven months, spent a lot of time on the set of his new movie 'Deadpool' and he hopes the bad language used in the film won't have had an influence on the tot, whose mother is his wife Blake Lively.

He said: "She's going to learn those words eventually anyway. If her first word is f**k, then I've done something wrong, but otherwise I think we're fine. I think we're OK.

"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."

Ryan was at Comic-Con in San Diego at the weekend and was very impressed with the lengths people went to in order to imitate his superhero alter ego.

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."

And Ryan thinks the film can live up to fans' expectations.

He promised: "It's got everything you ever want."

Meanwhile, his co-star Gina Carano admitted seeing the actor and his wife gave her "hope" because they are such "beautiful and nice" people.

She said: "I was so surprised to meet him and Blake and just find them to be the most pleasant well known celebrity-type people on the planet.

"They're so beautiful and so nice. It kind of gives you a little hope in the world."
