Jon Hamm and Catherine Keener get sentimental in exclusive 'Nostalgia' clip

— -- In Jon Hamm's latest star turn "Nostalgia," the former "Mad Men" star joins icons Bruce Dern, Ellen Burstyn and acclaimed actress Amber Tamblyn in a film about loss, the human condition and people's bonds with antique things.

"This is all junk, we don't need any of this," Hamm tells co-star Catherine Keener, who plays his big sister, in an exclusive clip for ABC News.

Keener's character is a little more sentimental and tries to tell her brother that this "junk," as he calls it, in the attic has value.

"These were [Grandma and Grandpa's] wedding present," she objects to his negativity.
