Five years have passed, but Joaquin Phoenix is back in the role that won him an Oscar – returning to play Arthur Fleck in new sequel Joker: Folie à Deux.

The new film hasn't been quite as well reviewed as the original across the board, but in our own 4-star verdict we called it "a brooding tale that works hard to reinvent the comic book movie" and praised the performances of both Phoenix and his high-profile co-star Lady Gaga, who joins the ensemble as Lee Quinzel, aka Harley Quinn.

The latter's presence has been especially commented upon ahead of the release, as has the fact that the film will be departing from the original by becoming a musical – or at least, musical inspired – with several classic songs heard throughout the runtime.

And while not too many stars other than Phoenix return from last time out (Zazie Beetz is a rare exception), the film does include a whole host of new names alongside Gaga, including Industry star Harry Lawtey and Alan Partridge himself, Steve Coogan – who plays a somewhat different TV personality here.

Read on for everything you need to know about the cast, including who they're playing and where you might have seen them before.
