BOSTON — Steve Martin, the actor and comedian, is guest curating an exhibition at Boston’s Museum of Fine Arts devoted to Canadian modernist Lawren Harris.

Martin will be on hand Friday for a preview of the exhibition, and he’ll discuss Harris’ work at Saturday’s public opening of the show. He is a passionate arts patron and collector.

Thirty Harris paintings will be on display, including landscapes of the northern shores of Lake Superior, the icy waters of the eastern Arctic and snow-capped Rocky Mountain peaks.

Martin says Harris deserves international acclaim for reaching “another level of the metaphysics of landscape.” Harris died in 1970.

“The Idea of North: The Paintings of Lawren Harris” runs through June 12.
