TIFF red carpet: Jon Hamm, Blake Lively and Jennifer Garner at The Town premiere

Like rare bird, Mad Men‘s Jon Hamm has become one of the more coveted celebrity sightings at this year’s TIFF. (We haven’t spotted him yet, but have been swooning vicariously.) Hamm is in TO to support Ben Affleck‘s The Town, which premiered last night. Also on the red carpet were Hamm’s co-stars Blake Lively, who was skipping out on some of New York Fashion Week, and Rebecca Hall, Canadian actress Rachelle Lefevre, and Jennifer Garner. Surely one of the evening’s best-looking red carpets. Click the images below to see pics or see all our TIFF 2010 red carpet galleries>>
