FILM crews have begun unloading props in preparation for filming to commence this morning.

Mystery still surrounds what is being filmed across two locations in Weymouth and Portland.

It is understood the filming is for season two of Apple TV comedy/drama Bad Sisters, but this has not been confirmed.

The series is written by, and stars Irish actress Sharon Horgan.

On Tuesday, film crews were setting up on Hope Street in Weymouth ahead of filming which is due to begin this morning.

A notice has been put up on Hope Street warning drivers that parking will be suspended for filming for six days, between Wednesday, March 13 and Tuesday, March 19.

Drivers and permit holders have been advised to park at the Nothe car park whilst filming takes place for six days.

Helen Moore spotted the crews on Weymouth Harbour.

She said: "At first I wondered what was going on because see lots of people in one place.

"I didn’t know they were a film crew until I walked around to the other side of the quay then they were film crew vans and I asked what was going on.

"It is good to see them in the town."

On Portland, film crews have also begun setting up at Weymouth and Portland National Sailing Academy, ahead of filming which is also due to begin on Wednesday.

Trailers featuring the ADF logo were seen in the car park in preparation for filming
