If true, this would be the first cast member announced for Star Wars: Episode VII which is due to start filming at Pinewood Studios in April, just two months away.
Driver would reportedly take on a similar role to that of classic Star Wars trilogy villain Darth Vader, and the delayed decision was due to scheduling conflicts with his current television roles for HBO's Girls which have now been resolved. Variety's source has said that the deal has not yet been finalised but should go through in the next few days.
In addition to Driver's role as Hannah's boyfriend on the hit HBO drama, his other credits include Inside Llewyn Davis and Frances Ha, and is currently filming Warner Bros' Midnight Special.
So far the only officially confirmed character for Episode VII is R2-D2.
