“I’m walkin’ here!” in Midnight Cowboy
Even if you haven’t seen Midnight Cowboy, you probably know the infamous quote, “I’m walkin’ here!” Dustin Hoffman delivered this line while walking alongside Jon Voight across a busy New York intersection. A taxi almost runs the pair over but stops at the last moment, sparking one of the most-recognized ad-libs of all time.
What people don’t realize is that the production crew didn’t get permission to film in New York. As such, they couldn’t stop and redirect traffic so as to not ruin their shots. So, when a taxi tried to run a red light and almost killed the two actors in the process, Dustin’s reaction was real though slightly out of character (he loses his accent for half a second).
