'50 Shades of Grey' movie news [RUMORS]: EL James mocks film set 'tension' with director Sam Taylor-Johnson on Instagram, Christian Grey & Anastasia Steele UPDATE

Earlier this week, E! News reported that there was some "tension" building up on the movie set of "Fifty Shades of Grey." Apparently, erotic authoress E.L. James and film director Sam Taylor-Johnson find such rumors utterly amusing.

An alleged source tells the popular gossip outlet, "Sam is getting annoyed about the way the script is being handled... E L James wants the movie to match the book exactly, but Sam has a different perspective."

The cast and crew (including Jamie Dornan as the kinky Christian Grey and Dakota Johnson as the stunning Anastasia Steele) are currently filming in Vancouver, Canada. The highly-anticipated S&M-inspired flick is scheduled for a summer 2014 release.

The insider continues, "Sam is reminding E.L. she writes books and she makes movies. This has caused some tension between the two of them." 

But this alleged "tension" doesn't seem to be an issue on Instagram...

erikaljames: "The gloves are off..."

Funny stuff.

So, how many fans are pumped to see the first film-installation of "Fifty Shades?"
