Poor chemistry causes '50 Shades of Grey' re-shoot?

Upcoming erotic-romance 'Fifty Shades of Grey' had to be re-shot reportedly due to lack of chemistry between the lead actors Jamie Dornan and Dakota Johnson.
The film is based on EL James novel of the same name, which traces deepening relationship between a college graduate, Anastasia Steele (played by Johnson) and a young business magnate, Christian Grey (Dornan).
The producers felt the footage was not passionate enough and as they have plans for the film's sequels they want it to be perfect, reported Aceshowbiz.
"Dakota isn't coming off sexy enough," a source said. "Ana needs to be naive, not a dish-rag. They want to do sequels, so this has to be perfect," another source added.

Last week, Dornan and Johnson were seen in woods near Vancouver to do-over their scene. He sported a black leather jacket and she donned a brown jacket. They were seen filming a kissing scene. Director Sam Taylor-Johnson was spotted on the set as well.
Universal Pictures, however, has denied reports of poor chemistry, saying the actors' intensity is unquestionable.
The film is due Stateside February 13, 2015. Luke Grimes, Rita Ora, Eloise Mumford, Max Martini and Victor Rasuk are among the cast.
