In the film, which revolves around a sentient robot who has to learn how to survive in a terrifyingly violent and dangerous underworld, Patel and Jackman both plays engineers but handle rival projects.
"I just loved working with him. He's probably the happiest actor I've ever seen on a set. That guy just bounds into work. He is in almost every scene of the movie, and his enthusiasm was incredible. He's obviously very brilliant, and smart, and just happy. His energy is completely contagious. I think he is a wonderful actor," Jackman said.
The 46-year-old Australian actor feels the 'Slumdog Millionaire' star's role is tough but he was commendable. "He's got an amazing quality that is infectious. He's incredibly believable, and it's a hard role to play. He's this sort of tech genius who becomes this father, this young parent, who has this proprietary feeling over this robot. It's really well played," Jackman said in a release by Sony Pictures India.
As they are pitted against each other on the film, Jackman said they didn't prepare much to bring out the aggression. He said it came naturally to them. "It was great, and he was totally up for anything. We were sort of ad-libbing a fair bit of that, and he was totally up for it. I just think he's brilliant. I loved working with him and I hope I get to do it again," he said.
Directed by Neill Blomkamp of 'District 9' fame, 'Chappie' is expected to hit theatres on March 13.
