In a recent interview, Adam McKay talked about out what a sequel to Talladega Nights: The Ballad of Ricky Bobby would've been about had the project ever happened.
"We did have an idea for 'Talladega Nights 2' It was that Ricky Bobby was going to hook up with an F1 team, and he was going to race in Denmark or the Netherlands and feel like he's in a communist country because they have nationalized healthcare," McKay said. "So, along with struggling with how fast those F1 cars go, he would have clashed with far-left-leaning Europe compared to America. The only reason we didn't do it was it's a lot of work to shoot race car stuff. The reason we went and did 'Step Brothers' next was we felt like, can we just go do comedy in a house? We were tired after 'Talladega Nights.' It never got to the point where we wrote a treatment."
