Apparently George Clooney is not one to take no for an answer. And that's probably why he was on his bended knee for almost half an hour during his marriage proposal to Human Rights lawyer and now wife Amal Clooney.

In a new interview with Vulture Magazine on Wednesday, the Hollywood actor recalled the moment by saying, "I asked her, and she just kept saying, 'Oh my, God,' and 'Wow,' and we just sat there. And finally, I just said, 'Listen, I'm 53 at the time, or 52 at the time, I think. I said, 'I've been on my knee for about 28 minutes so I gotta get an answer out of this because I'm gonna throw a hip out! I might not be able to stand back up.'"

The actor, who stars in the Disney film, Tomorrowland also explains why he's not keen on making summer blockbuster movies these days.

He said, "Well, I got a good taste of it in my mouth doing 'Batman and Robin.' 'Gosh, I'm so good at this, why don't I keep doing them?' You know, it's never really been my thing. Even something like 'Gravity' was a very different kind of film, where I wasn't carrying the bulk of the weight, and that wasn't even a summer film."

George added, "Other than that, it hasn't really been in my wheelhouse, quite honestly. I've been offered a few of them, but I didn't think I was the right guy for those jobs. But I have to say that 'Tomorrowland' didn't feel like a summer movie."

Tomorrowland hits theaters nationwide this Friday, May 22.
