Is there being too much pressure placed on the movie adaptation of the mega-hit bestseller 50 Shades of Grey? Some people think so, and believe that if the ship isn't righted soon, there could be a big screen disaster on the horizon.

First off is the matter of almost unattainable expectations. Suburban mothers the nation over have been scouring the internet daily for any semblance of news relating to the new movie, expected out in early August 2014. All of that pressure is weighing heavy on the minds of those involved, including the actress pegged to play the lead female role of Anastasia Steele.

"Dakota (Johnson) is having a very hard time dealing with all the press," a source told E! News "When she first got the role, it was way too much for her."

She's not the only one. Charlie Hunnam, the man set to play the role of super-hunk Christian Grey, has already backed out of the film just before shooting was to begin.

"The filmmakers of 'Fifty Shades of Grey' and Charlie Hunnam have agreed to find another male lead given Hunnam's immersive TV schedule, which is not allowing him time to adequately prepare for the role of Christian Grey," Universal Pictures said in a statement.

While that is possible, it also seems unlikely. Hunnam knew what his schedule was going to be like before signing onto the role, and at one point was eager to get things started.

"[Two] sources now say Hunnam got cold feet on the [Fifty Shades] movie, TV schedule said to have nothing to do with his exit," Matt Belloni, THR magazine's executive editor, tweeted last Saturday.

Money may also have been a factor in his decision to back out, as Hunnam was only slated to make $125,000 for his contribution to the movie. That's a paltry sum compared to what many leading men get for movies with the kind of name recognition of 50 Shades of Grey, and the small budget may point to doubt over how successful the film will be, further spooking Hunnam in the process.

Fan support is also a major issue that could haunt the success of a 50 Shades movie. So far a petition on Change.org that asks for the lead roles to be recast for Matt Bomer and Alexis Bledel has received almost 89,000 signatures in its support. With so many factors now working against it, will a 50 Shades movie be able to deliver at the box office?
