Boston Calling goes down 5/26-28, and one of the non-musical attractions was supposed to be a Natalie Portman-curated film festival. But today, Boston Calling organizers announced that a Hannibal Buress-hosted comedy show will replace Portman’s slot, which has been postponed for a future festival. The Boston Calling Comedy Experience will feature sets from Tig Notaro, Pete Holmes, and Eugene Mirman, among others. Check out the new Boston Calling lineup poster above.
