Although Stephen Sondheim expressed interest in creating a musical adaption of the film in 2003, he eventually concluded that " ... to make a musical of Groundhog Day would be to gild the lily. It cannot be improved." Nevertheless, Ramis announced in 2009 that Rubin was working on an adaptation. At a 2014 concert in Hyde Park, the Australian comedian and lyricist Tim Minchin performed a song he had written for the show, "Seeing You".
The musical was officially confirmed in April 2015, with a book by Rubin based on his and Ramis's original screenplay, directed by Matthew Warchus, choreography by Peter Darling, design by Rob Howell, and an original score and lyrics by Minchin. The production reunites most of the creative team behind the 2010 musical Matilda. It will be premiered in 2016 at The Old Vic theatre in London as part of Warchus's debut season as artistic director there. A Broadway debut is scheduled for March 2017.
