Due to a copyright argument, Jenna's BBC Four drama Room at the Top had to be put on hold while the copyright dispute was sorted out.
Room at the top is based on the classic novel of the same name by John Brain. The dispute is due to a confusion at Remus Films between whether or not the TV rights were sold to Great Meadow Productions by David Higham Associates.
Jenna plays the character Susan Brown in this two-parter which is 1 hour each. We don't know when to expect this to happen though but since it just "sitting on the shelf", we expect it to be soon.
