While the Marquez brothers often work onstage together, their first joint screen appearance was in the BBC television drama Hotel Babylon. Martin plays bartender Gino Primirola on the show, and John appeared in a guest role as his annoying brother. After filming Doc Martin VI, John appeared on stage in Privates on Parade at the Noel Coward Theatre, Ding Dong the Wicked at the Royal Court Theatre and Ragtime at the Regent’s Park open air theatre.
