Fans have criticised Daniel Radcliffe’s portrayal of “Weird Al” Yankovic in the forthcoming biopic Weird: The Al Yankovic Story.

The Roku Channel’s original film will act as an “untold true story” of Yankovic, documenting the singer’s rise to fame.

Taking on the form of a mockumentary, it will spoof troops that run rife in self-important biopics.

Following the release of its first trailer on Tuesday (3 May), fans have shared their scepticism on Twitter over the Harry Potter actor’s new role.

“Weird Al is 6 feet tall. Does Daniel do the entire film standing on a box?” one asked.

“Daniel Radcliffe will always be remembered for playing the role with glasses, untamed hair, and the wrong eye colour,” added another.

One fan wrote: “uhhh.... no. Just no. I love Daniel but this is not well cast.”

Some felt Radcliffe’s look was “too buff,” with a fan noting: “Al didn’t have pecs and abs like that back in the day that I remember.”

However, other commenters found the movie’s casting promising: “These comments are full of folks not getting the joke here.”

Additional cast includes Evan Rachel Wood, Rainn Wilson, Julianne Nicholson, and Toby Huss.

Weird: The Al Yankovic Story is scheduled to release later this year, with a specific date yet to be announced.
