Details about the "Sons of Anarchy" prequel have been limited online.  While fans are eager to get more information about Kurt Sutter's new show, rumors just keep on circulating about its cast and plot.

For many, the return of Charlie Hunnam as Jax Teller is a great treat.  Fans are definitely looking forward to see the hot biker reprise his role.  According to reports, there could be a great chance that the actor return as evidenced by him dropping out of some notable roles.

"The 35-year-old Hunnam backed out of 'Fifty Shades of Grey,' where he was slated to play Christian Grey," IBT reported. "His role in "The Mountain Between Us," opposite Rosamund Pike, was also offered to Idris Elba. There are rumours that Hunnam may also be moving out of the "Pacific Rim 2" movie due to his other commitments, such as being Green Arrow."

Meanwhile, fans were definitely delighted to hear rumors that Brad Pitt has allegedly been chosen to play a crucial role in the prequel.  According to reports, Pitt has been eyed to join the cast as John Teller, Jax Teller's father.

Pitt's character will be very crucial to the new show as it will reportedly focus on John Teller's early years.

"At some point I do have plans to hopefully do the prequel, which I do see as a one-off 10- or 12-episode thing where we begin in Nam and see John Teller and Piney and see how that relationship got created, and bring them back to the States and the obvious external dynamics that were going on with the country and the perception of the war and what an odd kind of perception these vets got when they returned home," showrunner Kurt Sutter told Deadline.
