Bill Murray will appear in new 'Ghostbusters'

Bill Murray will appear in the new, female-led Ghostbusters film.

The 64-year-old actor is confirmed to play an unspecified character in the upcoming reboot. Sources told Deadline the star recently "snuck" into Boston to film his scene for the movie.

Murray portrayed Dr. Peter Venkman in the 1984 film Ghostbusters, and reprised the character for the 1989 sequel Ghostbusters II. The actor has long been reluctant to star in a third movie, but showed his support for a female-led cast last year.

The forthcoming reboot is directed by Paul Feig, and stars Kristen Wiig, Melissa McCarthy, Leslie Jones and Kate McKinnon. Murray and McCarthy previously collaborated on St. Vincent. Ghostbusters opens in theaters July 22, 2016.

Wiig, McCarthy, Jones and McKinnon are filming in Boston, and visited Tufts Medical Center in costume earlier this month. Murray last appeared in Aloha with Emma Stone, and is also scheduled for Rock the Kasbah with Kate Hudson.
