Jason Bateman and Will Arnett played host in NYC last night at a bash celebrating the launch of DumbDumb, their new venture that strives to "create commercials along with short and long form programming for distribution across all platforms."

Will's pregnant wife, Amy Poehler, was also present, after their family left LA to be in the Big Apple for Internet Week.

His Summer blockbuster arrives in theaters today, and Buzz thinks Bradley has another hit on his hands.
