Harry Potter star Jessie Cave, who played Lavender Brown, is in the DogOrange theatre company’s production of Mary Rose. New promotional stills, courtesy of Snitchseeker.com, and a trailer can be seen below.

The play, which is adapted from the novel written by Peter Pan author J.M. Barrie, is a supernatural story of love, lost innocence and the parallel world of the dead. Time Out had this to say about the play.

A scrupulously detailed, gripping, genuinely goose-bump inducing vision of this high Victorian ghost story … director Matthew Parker’s sterling cast, and his sure, hugely inventive dramatic touch generate an impressive, lingering impression of real loss and longing.

The play runs from now until April 28, 2012 at Riverside Studios in the UK. If you reside in London or will be there during this time, you can purchase tickets for the show here.
