The classic film, The Rain Man, has been adapted for the stage and we have four tickets to give away to see it in Cambridge featuring two popular TV stars.

Actors Mathew Horne (Gavin and Stacey) and Ed Speleers (Downton Abbey) star in the adaptation of the Oscar-winning movie that featured Tom Cruise and Dustin Hoffman .

When self-centred salesman Charlie Babbitt (Ed Speleers) discovers his long-lost brother Raymond (Mathew Horne), an autistic with a genius for numbers, has inherited the family fortune, he sets out to get his half.

Charlie ‘borrows’ Raymond from the institution where he has spent most of his life and the two brothers embark on a trip across America.
