The acting world lost one of its biggest talents - and the general world an amazing human - after Alan Rickman passed away aged 69 this week.
Tributes have been pouring in from his colleagues and co-stars, all of whom reiterate just how wonderful he was to work with.
While the ultimate professional, Alan had a wicked sense of humour too - as this video from the Harry Potter set shows.
The behind the scenes clip sees Alan and Michael Gambon, who played Dumbledore, well and truly pranking Daniel Radcliffe during the filming of a scene in the Great Hall.
Snape and Dumbledore cracking up will literally never get old.
If you liked that, you'll also love this Harry Potter bloopers reel too, featuring Rupert Grint and Emma Watson laughing every time they have to film *that* kiss and other such joy.
