Having hatched a brood of popular spin-offs, including books, toys and a TV series, the blockbuster video game franchise is turned into a boisterous animated movie.

The story is a pretty bird-brained affair, but it does entertainingly explain why the birds and the green pigs become enemies.

The film also launches a barrage of avian and porcine puns, plus a flock of knowing pop-culture references. Most of these will fly right over the heads of younger viewers, but the film’s rambunctious silliness will go down a treat.

Among the voice cast, listen out for Jason Sudeikis as hero Red, Josh Gad, Danny McBride and Maya Rudolph. Sean Penn’s rumbling growls may be harder to detect, but his casting is a stroke of genius.
