A building on movie mogul GEORGE LUCAS' Skywalker Ranch estate in northern California was damaged by fire on Tuesday morning (03Sep13).
Reports suggest a broken electric motor in a ceiling fan was the cause of the blaze, which began at around 4.30am local time.
No one was injured in the fire, which was quickly contained.
Marin County Fire Battalion Chief Mike Giannini described the damage as minimum to moderate.
The film is almost half an hour longer than 'The Force Awakens'.
The actress will no doubt be returning for the long-running FX series.
The film is expected to continue without Mendes' involvement.
