Speaking to the Wall Street Journal, Carnahan suggested that the blockbuster - which made just $77 million at the US box office - wasn't marketed well enough by 20th Century Fox.
"We kind of fell victim to a marketing misstep in that there wasn't necessarily an understanding of what the show was," he said. "We didn't do an adequate enough job of telling people what the movie was, if you know what I mean."
Carnahan claimed that, despite a lack of clarity in the ad campaigns, he received positive feedback from people who went to see Liam Neeson, Bradley Cooper, Quinton Jackson and Sharlto Copley in the action film.
“If I had a nickel for every time someone, especially women, came up to me and said they were dragged to the film but ended up liking it...” he commented. “That’s how you know you blew it. And we blew it. Hopefully, we can make it up and find the audience the film should have found during the summer on Blu-ray and DVD. Fingers crossed.”
When asked about the chances of seeing an A-Team sequel, Carnahan said that "a large degree of it depends on how it does in this [DVD/Blu-ray] realm".
