Why her: The Vancouver actor best known for playing Robin on How I Met Your Mother and Agent Hill in The Avengers has enough star power to host an awards show and has an especially high profile among the younger audience the Junos hope to capture. She also may be available before The Avengers: Age of Ultron begins production. Why not: Given Smulders’ U.S. film and television success, there may not be any upside in hosting a Canadian show. Odds: A long shot. You may have to content yourself with Smulders’ next turn as Hill in Captain America: The Winter Soldier, which comes out March 26.
