After musing yesterday about the past year’s crop of biopics that used the hoary genre somewhat subversively or at least differently, I watched another one.

Weird: The Al Yankovic Story is a fake biopic of a real person. It parodies the genre thoroughly in form, except that most of the factual information is made up. It’s a mostly hilarious movie—soon to be a stoner classic—that incorporates every biopic cliche you can name. Daniel Radcliffe is a delightful Al, in a performance at least as credible, if not more credible, than Rami Malek’s in the awful Bohemian Rhapsody, which is strange because Radcliffe’s Al is fake. Evan Rachel Wood is also great as Madonna, and super sexy doing it. Naturally, there are billions of funny cameos and many more people playing celebrities. And tons of great Weird Al music.

The main weakness of the film is the directing. It’s competent, in that the film is still a lot of fun, but it underserves the script by being boring and sometimes too slack. And it really underserves Radcliffe, who seems to be having a great time, by failing to match his energy.

But the central conceit of making a biopic of a real person but lying about nearly all the personal details is a masterstoke.
