Aaron Paul told his friends he was making a "small little indie project" when he was really working on 'El Camino: A Breaking Bad Movie'.
The 40-year-old actor reprises his role as Jesse Pinkman in the Netflix film but work on the project was kept secret so he enjoyed "lying" to people about what had been keeping him busy.
He said: "I love surprising people, I love lying to people, you know, it's easy for me.
"We had a fake name for the film. I told my wife, obviously, and my parents, and a couple of my friends, but everybody else, I said I was doing a small little indie project in New Mexico and no one second-guessed it."
