Marcel eventually quit acting to pursue writing, while working part-time in Prime Time Video, a video rental shop in Battersea, London. Around the corner from the video shop was the Latchmere pub, where Tom Hardy hosted an acting workshop. Marcel and Hardy became friends, and he subsequently brought Marcel in to do uncredited rewrites on his 2008 film Bronson, directed by Nicolas Winding Refn, after it ran into trouble. One of Hardy's tattoos says 'Skribe' in tribute to Marcel.
