The text he added via Instagram:

An illicit picture of Dan and Rupert under the invisibility cloak in Hagrid's hut. It's patronising but true that it's hard to see it without thinking how utterly adorable they were. Are. Things were very strict on set and I felt ashamed and scared but couldn't stop myself wanting a record. Nowadays we'd be selfying from morning till night #WishIdTakenMorePix @HarryPotter @harrypotterfilm
