David Walliams was one of the first to pay tribute to Rik Mayall, who died this morning, aged 56.
"I am heartbroken that my comedy idol growing up Rik Mayall has died. He made me want to be a comedian," said Walliams on Twitter before sharing a clip of the actor as Lord Flashheart in Blackadder.
Mayall's management firm Brunskill Management said the comedian died at his London home on Monday.

"RIP Rik Mayall. Thank you for making me laugh a million times. Woof," said Chris Moyles, while Chris Evans said:
"RIP Rik Mayall. I'm off to hit the gasman with a frying pan. It's the least I can do," he wrote on Twitter, referring to Mayall's famous slapstick comedy.
"Rik Mayall spread a lot of fun and laughter," said author and playwright Irvine Welsh. "Very sad to see him taken before his time.
