What if Robert Eggers' The Lighthouse was an oddball stoner comedy? Well, you'd get something like this. Ebony & Ivory shares similarities with the real life chart-topping hit—the film features caricatures of the song's singers, Paul McCartney and Stevie Wonder. But that is where the similarities end in what is undoubtedly the weirdest film of the year.

A biopic, this is not. Paul and Steve really did record the single on an island, but in Jim Hosking's film, the pair (played by Sky Elobar and Gil Gex) meet on a remote Scottish island to argue, smoke pot, and eat veggie ready meals. That's as much as you're getting in terms of plot. This isn't an exploration of how they created the titular song—Paul and Stevie don't even make any music together—but a bonkers fever dream.

It's immediately apparent what tone Ebony & Ivory is aiming for. Individual shots and entire scenes go on for far too long, Elobar and Gex's delivery is deadpan in the most unsettling way, and most conversations go round and round in circles before moving on to the next insane bit. There will certainly be audiences who will view this 85-minute experience as torture—but tune into the film's strange frequency, and you might get something out of it.

Gloriously goofy, it's knowingly absurdist and anti-comedy; there's clear intent behind Hosking's wacky direction. And there's clearly love and attention to detail too. The 80s production design of the Scottish cottage the music legends reside in feels lived-in, and the faux branded drink and food they consume is hilariously realised. Not every joke lands, but there are certain sequences and gags that made this reviewer laugh out loud—from veggie nugget slides to the most ridiculous prosthetic penises.

With Paul and Steve carrying the movie, it's a blast seeing Elobar and Gex get weird with their lead roles. Elobar plays Paul as someone who knows McCartney only through Wikipedia entries and celebrity impersonations. Gex, on the other hand, completely avoids re-enacting any semblance of Steve—which is all the more funnier when his character is an unpredictable firecracker. A shoutout must go to composer Andrew Hung and his lively electronic score.

Ebony & Ivory is juvenile and plain weird, yes, but it's a fun hangout movie. Everyone involved in the making of the film is clearly committed to the bit, and there's joy in not quite knowing what crazy sequence will come next. With The Greasy Strangler, An Evening with Beverly Luff Linn, and now this, Hosking proves that his work isn't for everyone, but it sure is singular and unique.

Ebony & Ivory is in UK and Irish cinemas on 19 September.
