Wild Mountain Thyme is a 2020 romantic comedy film written and directed by John Patrick Shanley, based on his play Outside Mullingar.

The film stars Emily Blunt, Jamie Dornan, Jon Hamm, Dearbhla Molloy and Christopher Walken.

Tony plans to disinherit Anthony, as he fears his misanthropic son will not marry and have children, leading to the end of the Reilly legacy.

It was announced in May 2019 that John Patrick Shanley would write and direct an adaptation of his play Outside Mullingar, starring Jamie Dornan and Holliday Grainger[4] By August, Emily Blunt, Jon Hamm, Christopher Walken and Dearbhla Molloy were added to the cast, with Blunt replacing Grainger in her role, and Molloy reprising her role from the play.

[10][11][12] Shanley stated that no one would understand the characters if they sounded like his relatives spoke, and "you have to make the accent more accessible to a global audience".

The soundtrack album was released digitally in December 2020, featuring Amelia Warner's score and an original song by Sinéad O'Connor.

The website's critics consensus reads: "Fatally undermined by dodgy accents and a questionable story, Wild Mountain Thyme is a baffling misfire for a talented filmmaker and impressive cast.

[17] David Ehrlich of IndieWire gave the film a "C−" and wrote: "Shanley, whose script for Moonstruck suggests that he once had a slightly tighter handle on this sort of thing, brings his play 'Outside Mullingar' to the screen like he's trying to fill every close-up with enough whimsical enchantment to reach the back row of a Broadway theater.

The lethal intensity of this effect cannot be overstated; the only logical explanation for what happened here is that someone planted a bomb in Shanley's editing bay and timed it to explode if any cut of Wild Mountain Thyme dipped below 50 kilohertz of cartoon Irish charm per minute.

[19] Mick LaSalle of the San Francisco Chronicle gave the film a positive review: "The gentle spirit of Wild Mountain Thyme envelops us early, to the extent that, midway through, even though there is very little left to resolve, we are in its spell.

[23][24] Karen Han of Slate drew comparisons between the protagonists' identities and that of furries,[25] and wondered if John Patrick Shanley intended to portray the characters as otherkin.
