A sequel was ruled out shortly after the film's release in 1993.[102] Rubin also holds a story credit on the 2004 Italian remake of Groundhog Day, called È già ieri (translated as It's Already Yesterday), and commonly known as Stork Day.[6][40] When asked about a sequel in 2018, MacDowell said it would never happen because "I know [Murray]. He's not going to do it."[205] Despite this, Murray, Tobolowsky, and Doyle-Murray reprised their roles in a commercial for the Jeep Gladiator played during Super Bowl LIV on February 2, 2020. Filmed in Woodstock, the commercial recreates scenes from the film, and features Murray again trapped in a time loop. He uses the Jeep Gladiator to explore Punxsutawney alongside Punxsutawney Phil.[206][207] Murray called it his first and last commercial.[208] In April 2020, Jeep released a series of modified versions of the advert to promote social distancing during the 2020 COVID-19 pandemic. Murray provided creative input on the edit.[190][209]
In the years since the film's release, Rubin had worked on a musical adaptation of Groundhog Day, partly out of boredom and partly because a musical was not covered by the rights he had signed over to Columbia.[4][6] In 2003, Stephen Sondheim expressed interest creating a musical but this project was never realized.[210] When Matthew Warchus and Tim Minchin approached Rubin in 2012, he had already developed a narrative outline, jokes, and a refined list of 12 songs.[4][6] He had been unable to progress the idea further without a composer. Coming off the success of Matilda the Musical, Warchus and Minchin collaborated with Rubin for several years to produce the Groundhog Day musical.[6] The musical debuted in August 2016, at The Old Vic theatre in London to generally positive reviews.[6][211] A Broadway version started running in 2017.[212] The show was nominated in several categories at the 2017 Laurence Olivier Awards, winning Best Actor and Best New Musical.[213] Murray attended a Broadway show in 2017, alongside Doyle-Murray and Rubin.[214]
A video game narrative sequel was released in September 2019. Groundhog Day: Like Father Like Son was developed by Tequila Works and published by Sony Pictures Virtual Reality for PlayStation VR, Oculus Rift, and HTC Vive. The game casts players as Phil's son, Phil Connors Jr., who has grown up in the shadow of his beloved father. Phil Jr. becomes trapped in his own time loop in Punxsutawney and is forced to help others and improve himself to earn his freedom.[215][216][217] It received mixed critical reviews.[218]
