This was the lancaster in their first feature length film lancaster skies filmed at that time in a converted cow shed but that took them five years to complete. i hear you re a spitfire pilot. so while dad andy was building bits of spitfire in his shed, callum was learning how to do visual effects upstairs on his computer. this film is a more scaled back story about a lone pilot with the raf photo reconnaissance unit, whose mission was to provide photographic intelligence for the allies. but local lad archie still got a part. so i think it was from when they started drinking in my mum and dads pub, which is just down the road, and then the relationship kind of built from there. and that s solely how i mainly got the role in spitfire. so we hope we haven t spoilt the magic for you just impressed you with a father and son s innovation. look out for a limited cinema release next month, and then a release on streaming services injune. simon spark, bbc news.
