Weird Al Yankovic has given a first look at Daniel Radcliffe in costume as him for a TV biopic, joking that he had the Harry Potter star thrown out by security.

Radcliffe is set to star as comedy singer Yankovic, 62, in WEIRD: The Al Yankovic Story, which will air on streaming service Roku, and the comedian posted a sneak peek at what's to come in the story of his life.

He tweeted a picture from set where Radcliffe is barely recognisable, playing a keyboard accordion and wearing a Hawaiian shirt, glasses, and with a curly mop of hair.

Yankovic captioned it: "SHOOT DAY #8: It never fails – we’re trying to shoot a movie here, and this cosplayer weirdo tries to crash our set.

"Ugh! I mean, I love my fans, but… boundaries, people! Don’t worry, we had security throw him out."

Yankovic is the biggest-selling comedy recording artist of all time and has won five Grammy awards.

His 2014 release Mandatory Fun was the first comedy album in history to debut at number one on US music chart Billboard’s Top 200.

Celebrities including Jack Black, Seth Green and Donny Osmond have appeared in his music videos.

Production on the biopic, which will chart his rise to fame creating spoof versions of popular songs, began in Los Angeles in early February.

Yankovic previously said he was "thrilled" to be portrayed by Radcliffe and joked that the film would be "the role future generations will remember him for."

Last year, Radcliffe, 32, admitted to being "intensely embarrassed" by some of his acting in the early years of his career on the Harry Potter films where he first found fame.
