Not only do we already know that Bill Murray is a big music fan, but he seems to get cooler and cooler every time we hear from him.

The comic legend stars in the upcoming 'St. Vincent,' and he also appears in a comical promo video for the movie that surfaced earlier today. In the clip, Murray listens on his headphones to the Bob Dylan classic, 'Shelter From the Storm,' and sings along while smoking and attempting to water his one plant. Check it out below.

The film, which also stars Melissa McCarthy, Naomi Watts and Chris O'Dowd, is about a young boy who finds an unlikely friend and mentor in a misanthropic veteran who lives next door (Murray). 'St. Vincent' hits theaters on Oct. 24.
