Outspoken LGBT ally and actor Samuel L Jackson has signed on to tackle his first ever role as a gay character in an upcoming film adaption of Stephen King’s ‘Cell.’

Variety reports Jackson will portray Tom McCourt, an openly gay engineer who used to serve in the army.

In King’s novel, McCourt flees Boston alongside New England Artist Clay Riddell, who is desperate to reunite with his son after a phone signal turns the Earth’s population into mindless vicious animals.

Clay Riddell will be played by John Cusack, and the film is to be directed by Tod Williams, who is best known for his work on Paranormal Activity 2.

Samuel L Jackson was among the many Hollywood celebrities, including Brad Pitt, Stephen Speilberg, and Tom Hanks, to speak up when California passed Proposition 8 in 2009, which was a law banning same-sex marriage in the state.

The previous King adaptation, 1408, also starred both Cusack and Jackson.
