Riley is a writer/director.

Currently, he has been selected for the 12-month long London Voices scheme run by BBC Writersroom. Prior to this, he developed the TV pilot script 'The Haven' as part of the BEA Script Editing Initative also led by BBC Writersroom. He wrote and directed the short film 'Lifelessnessless' (currently in post-production), which was developed and supported by B3 Media's TalentLab Scheme.

Previously, he wrote and directed the short film, 'Sleep Tight, Don't Let the Existential Crisis Bite!', which was selected for eight film festivals, awarded 'Best Screenplay' at the Rob Knox Film Festival, and nominated for 'Best International Film' at the Houston Comedy Film Festival. 

He continues to write and direct short films; as well as writing long ones, and medium ones too.

Outside of writing, he likes to play Dungeons & Dragons and spend time chatting with his tuxedo cat Monty (who is definitely a human in disguise, he believes).​
