"I was very impressed with how they made the movie," Robertson told The Christian Post in an interview on Friday. "I would definitely say my own faith was strengthened – I was glad to be on the side of the kid defending his faith."
Robertson, along with his wife Korie, are in the upcoming film playing themselves. The reality star says he was delighted on how well the movie came together.
"I've seen some Christian movies where the acting's not as good or the story's not as good, or it's just a lower budget film," Robertson admitted. This film, however, "really raised the bar with these faith-based movies."
However, the "Duck Dynasty" star noted the difference in the shooting of the reality show from the feature length movie.
"Duck Dynasty's a totally different show – it just follows our lives around," the star told CP. Filming for the TV show has made his family more comfortable on camera, it did not drastically alter his day-to-day life.
The A&E reality show "Duck Dynasty" shows the life of the multimillionaire family the Robertson's. The popular reality series known for ending each episode in prayer, has been a huge success for the network with $80 million in advertising sales for the first nine months of 2013.
