But Pitt remained tightlipped in his response: "No, not yet! Top secret."
Brundle then asked Pitt - who kept on walking - if he had been enjoying himself and noted how he had seen him around throughout the week.
"Thank you, man," Pitt replied and continued to walk away.
"Obviously they’re known as ‘pitt stops’—if they don’t want you talking to Brad Pitt," Brundle quipped, making light of the snub.
However F1 fans were less than impressed with Pitt and felt that the actor should have chatted with Brundle since he is known as the "voice of the sport" - especially given that Pitt is making a movie all about F1.
\u201cBrad Pitt making a movie about F1 but not knowing who the voice of the sport Martin Brundle is\ud83e\udee0\u201d
\u201cWhen you\u2019re at a Formula 1 Grand Prix you\u2019re a guest of Martin Brundle. Respect the man. Brad Pitt was completely out of touch ignoring Martin and having his guys pull him back. Last time it happened with other American celebrities at the Miami GP \u201d

\u201cBrad Pitt, you're doing a movie on F1 and don't know who Martin Brundle is? It's *the* grid walk. Stop and talk to him.\u201d

Though this year Brundle had better luck with singer Ed Sheeran who described his first Grand Prix as a "fun" and "new experience," and described how he was "super excited to be back" in America, performing his first show in five years when he headlined the F1 Grand Prix concert.
