At one point in The A-Team, the BA character is high up on the side of a building, pretending to wash windows.
When he starts to whistle, the audience naturally assumes he is whistling the theme tune that's certainly what is suggested in the trailer.
Quinton Jackson says otherwise though, and initially it was only his family members who caught the in-joke.
Jackson says his dad never did quite get the hang of whistling and he's simply imitated his dad's hum/whistle noise, which pleased the old man immensely.
"My character was a mixture of me and my dad. He takes a straw from the broom and he tickles his ear and he goes doo-doodle-doo," said Jackson.
The 32-year-old mixed martial artist says he worked on this film |for his dad and it certainly was a dream come true to portray the character originated by one of his heroes, Mr T.
The Memphis native originally wanted to go into professional wrestling and segued into mixed martial arts, gaining fame in the US in the Ultimate Fighting Championship (UFC) but it's the reality show - The Ultimate Fighter - that's really gained him notoriety.
He's had to learn to tone down the tough talk which no-one takes too seriously on the fighting circuit now that he's stepping into an acting role.
"Coming from a fighter world, what I can say about acting? It's totally different. When we fight we don't have people doing our hair and make-up," said Jackson, who is currently in South Africa to promote The A-Team.
He had to sit through three hours of make-up to cover up his tattoos and hours of grooming to get the mohawk just right, but still, he thinks acting is fun.
"You get to be like a kid, you get to pretend to be someone you're really not, do things that you really can't do in real life. But there's a lot of behind-the-scenes stuff that goes along with acting that's totally different for me.
"Basically I'm a fighter and in fighting you can say whatever the f**k you want, you can talk bad about your opponent. I'm used to that."
Jackson toyed with the idea of retiring from the fighting world altogether while making this film, because being on set clashed with his commitments to the UFC. While he'd initially not agreed with the BA story arc, which called for the character to renounce violence at one point in the movie, this made sense to him at the time.
"That scene for me was so surreal, it was so real for me.
"Basically I was saying exactly how I was feeling.
"I didn't wanna fight no more. At that point in the movie, I actually fell in love with acting."
This having been his dream role means he's not exactly looking for more work.
"I've played BA Baracus. If I don't ever get another movie, I'm okay with it, I'm not going to cry because I can still fight. I never set out to be a movie star or a famous person. It seems like The A-Team has really made some dreams come true for me."
