Liza Marshall has quit her job as Channel 4's head of drama and is gooing to work for Scott Free, the production company founded by director brothers Ridley Scott and Tony Scott.

Channel 4 head Julian Bellamy said: "Channel 4 drama under the leadership of Liza Marshall has consistently punched above its weight with challenging and ambitious work including The Devil’s Whore, Boy A, Mark of Cain, Skins and Shameless. We wish her well in her exciting new role and the search now starts for her successor".

Ridley Scott, meanwhile, says this: "At a time of uncertainty in many areas of the business, and in particular in the speciality film sector in the US, we believe it is an opportune time to step up our commitment to European film-making. Liza’s appointment enables us to offer a real home for creative talent and help them navigate the new business models which will be needed to get films made".
