Siner is fondly remembered by fans of classic Doctor Who for his fine turn as the inexperienced Kaled General, Ravon, alongside Tom Baker's Fourth Doctor in the seminal story Genesis of the Daleks. But his sci-fi credentials don't stop with the retelling of the Daleks' origins, he was also a voice artist in several Star Wars computer games, including Force Commander, Galactic Battlegrounds and Jedi Knight II: Jedi Outcast. Siner's work in computer games is an important reminder that the Star Wars galaxy doesn't end with the films. Stories in other media are essential elements of that fictional universe, too.
