"I was in Canada when I got the call for the film and without even reading the script, I immediately said, 'Yes, I will definitely do it'," the 40-year-old said here in an interview.
"This is because when I came to Mumbai 10 years ago, I met Rameshji (Taurani) and asked him, 'When will I get a film?' And he said, 'Very soon.' But it took him 10 years to take me (in a film)," added Sonu, who has also been signed by Taurani for an Akshay Kumar-starrer.
In "Ramaiya Vasta Vaiya", set for July 19 release, Sonu plays Shruti's strict brother.
