The theatrical release poster for Due Date shows Zach Galifianakis holding a dog.
More specifically, the poster depicts Galifianakis’s character, aspiring actor Ethan Tremblay, holding a bulldog wearing a protective cone around its neck. He stands beside Robert Downey Jr., whose character, Peter Highman, is trying to reach Los Angeles before the birth of his child.
Due Date is a 2010 road comedy directed by Todd Phillips, who later directed The Hangover trilogy and Joker. The film’s central comic pairing is built around the anxious Peter and the eccentric, unpredictable Ethan, whose dog becomes part of the increasingly chaotic journey.
The answer is sometimes remembered as “a bulldog,” but “a dog” is the broader and fully correct answer requested by the quiz. The poster’s dog is also easy to confuse with the film’s other memorable travel mishaps, including airport trouble and a cross-country trip through the American Southwest.
