The 37-year-old, who has a one-year-old son Vivaan Veer with his wife Priyanka Alva, was quizzed by the nine-year-old on questions ranging from his childhood to the experience of being a father.
"Captain Tiao", which will see Sadhil interviewing many big names, will premiere on Disney Channel March 2.
The star of films like "Grand Masti" and "Shootout At Lokhandwala` was bowled over by Sadhil's inquisitiveness and energy.
"It was a fantastic experience. Captain Tiao's eagerness, inquisitiveness and energy is extremely infectious and to be interviewed by this inquisitive little fellow took some getting used to, but that is what made it more fun," Vivek said in a statement.
"More importantly, I feel like the interaction was a practice session for me to face many more such questions that will definitely come my way as my own son grows up," he added.
