These behind the scenes shots of Endeavour are from the first day of filming in Oxford for Episode 3 of Series 4. This was the first scene they filmed in the morning of Dr Max DeBryn cycling around Radcliffe Square but it didn’t make the final edit. I’ve cycled over those cobble stones and it’s not comfortable at all.
