Don’t feel bad if you didn’t realize that Paul Bettany was the voice of artificial intelligence Jarvis in “Iron Man” – he didn’t know either!

Bettany said he got a call from pal Jon Favreau, who was fuzzy on details, but convinced Bettany to do a bit of voice work for his upcoming film.

“I didn’t know I was in a superhero movie,” Bettany told SuperheroHype.com. “[Favreau] rung me up and was really funny on the phone. I said, ‘Yeah, alright.’ I genuinely didn’t know. I’m really naive, but it’s the f**king truth. I really didn’t know what I was going in for because it was two hours in a recording booth. I went in and recorded with Jon Favreau, doing all the lines, recording them and went home and now I’m a f**king hero to my children. I haven’t even seen it yet. I haven’t had time because I’ve been working for 17 hours [a day].”

Bettany is currently filming “Legion” with Dennis Quaid.

Jon Favreau and his wife, Joya Tillum, have welcomed their third child together.

E! Online reports that the couple welcomed baby Girl, Brighton Rose, on Tuesday. Favreau confirmed the birth on his My Space page.

“Last night I had my third kid. Her name is Brighton Rose Favreau and she’s doing great,” Favreau wrote on his My Space page on Wednesday.

According to People, the baby was born at Cedars-Sinai Medical Center in Los Angeles and weighed in at 6 pounds, 13 ounces and measured 18.5 inches.

The couple’s other two children are three-year-old Madelaine and five-year-old Max.
