Tristan has produced/directed over 30 films since his first film in 2007, the feature length documentary ‘Welcome Aboard Toxic Airlines’ (2007). This particular film triggered two calls for a public enquiry into the issues of contaminated air on aircraft in the UK. The documentaries ‘Shady Lady’ (2012), Everybody Flies (2019) and ‘American 965’ (2021) and short films ‘Missing a Note’ (2019) and ‘Finding Wilson’ (2021) were long list contenders at the Academy Awards. ‘A Dark Reflection’ (2015) is reported to be the last feature film shot on Fuji 35mm film stock and Britain’s biggest co-operative film to date. He also produced the short 'Ellston Bay' (2018) shot on VistaVision.
He is currently working on the short 'Aguska' and a number of feature length documentaries
