Ever had that one ex you just can't quit? The kind where even years later, a single chord strummed on a guitar sends you spiraling back into nostalgia? That's the deliciously awkward premise of The Ballad of Wallis Island, the upcoming comedy-drama from Focus Features that just unveiled its brand-new poster. And let me tell you—this film looks like it's going to be equal parts hilarious, cringe-worthy, and unexpectedly moving.
Breaking Down the Poster
The design is a clever mix of indie charm and mainstream appeal:
- Bold, hand-drawn lettering gives it a whimsical, almost folk-art vibe.
- The tagline hints at the film's core conflict: a superfan (Tom Basden) dragging his favorite broken-up band back together.
- The cast names—Mulligan, Basden, Key—are front and center, signaling this is as much an actor's showcase as it is a comedy.
The Story: Awkward Reunions & Second Chances
Directed by James Griffiths (The Man Who Invented Christmas), the film follows Charles (Tom Basden), an eccentric millionaire who lures his favorite former band—Mortimer-McGwyer—to his private island for a one-night-only reunion. The catch? The band's core members (Carey Mulligan and Tim Key) are ex-lovers with plenty of unresolved baggage.
If that setup doesn't scream “comedy gold,” I don't know what does. The official synopsis promises old tensions resurfacing, desperate attempts to salvage the gig, and presumably, a lot of passive-aggressive lyric-writing.
The Cast: A Dream Team of Comedy & Drama
- Carey Mulligan (Oscar-nominated for Promising Young Woman) as one-half of the estranged duo.
- Tim Key & Tom Basden (both Plebs alums) bringing their signature dry wit.
- Sian Clifford (Fleabag's long-suffering sister) and Akemnji Ndifornyen (The Queen's Gambit) rounding out the ensemble.
With this mix of dramatic heavyweights and comedy maestros, The Ballad of Wallis Island could be the perfect blend of heartfelt and hilarious.
Release & Expectations
After premiering at Sundance 2025 to (reportedly) strong buzz, the film hits theaters March 28. Given Mulligan's track record of elevating every project she touches, plus the sharp writing of Basden and Key, this could be one of the year's sleeper hits.

There's something inherently compelling about stories of faded musicians forced to confront their past—Once, A Star Is Born, even Bohemian Rhapsody all tap into that bittersweet magic. The Ballad of Wallis Island seems poised to join those ranks, but with a wry, British-comedy twist.
Will it be a crowd-pleaser? Almost certainly. Will it also have moments of real emotional depth? If Mulligan's involved, count on it. The only question is: Just how awkward will that reunion get?
Keep an eye on this one. It's got heart, humor, and Carey Mulligan singing—what more could you want?
