"Fifty Shades of Grey" cast Jamie Dornan celebrated his birthday on May 1 as the actor who plays Christian Grey is reportedly losing his mind due to the popularity and hype surrounding the upcoming film.

The tabloids are in the dark on how Jamie Dornan spent the day he turned 32 but according to E! News, it's presumably with his wife Amelia Warner and their baby girl.

"Fifty Shades of Grey" will open to theaters on February 13, 2015.

The official social media site of "Fifty Shades of Grey," tweeted: "Happy 32th Birthday to our Beloved Christian Grey, James 'Jamie' Dornan. @JamieDornan1 ♥ xoxo :')"

Meanwhile, "Fifty Shades of Grey" cast Jamie Dornan told The Guardian that the hype surrounding the upcoming movie is getting out of hand.

"It's just all a bit silly the way it works. I think I could lose my mind," he said, adding that it's "ridiculous" the amount of attention he's getting by portraying Christian Grey.

According to inquistr.com, the adaptation of the erotic novel penned by E.L. James has become one of the most anticipated movies in recent memory. And Universal Pictures is taking advantage of the hype by scheduling the movie's release a day before Valentine's Day.

"Fifty Shades of Grey" cast Jamie Dornan was hesitant at first to accept the role for fear of being typecast. The New York Daily News said that he's hoping to get some roles in the future that don't involve denigrating women.

Part of the hesitation was probably because the film requires a lot of nudity and sex scenes, which Dakota Johnson, who plays Anastasia Steele, has no problem doing.

In the March issue of Elle magazine, "Fifty Shades of Grey" cast Dakota Johnson anticipated doing steamy sex scenes and being naked before accepting the role of the main character. However, she saw no problem with what the role requires because of her biggest "secret."

"The secret is I have no shame," said the daughter of actors Melanie Griffith and Don Johnson.
