Chennai, Sep 15 (IANS): Actor Rana Daggubati won't be able to attend the grand audio launch of filmmaker Shankar's Tamil magnum opus "I", where Hollywood star Arnold Schwarzenegger is the chief guest.

Rana, who was invited as a guest for the audio launch Monday, is off to Abu Dhabi to shoot for Neeraj Pandey's Akshay Kumar-starrer "Baby".

"Won't be able to make it to the 'I' audio launch this evening because of shoot. Will be missing a huge event. Missing a chance to see the legands on stage @Schwarzenegger and @superstarrajini," Rana posted on Twitter Monday.

Schwarzenegger landed in Chennai Monday morning to attend the event, which will also be graced by cinema legend Rajinikanth.

Aascar Ravichandran-produced "I", which was earlier titled "Ai", features Vikram and Amy Jackson in the lead roles. It is reportedly made on a budget of Rs.180 crore, and has been on floors for nearly two years.

The film's post-production work, featuring a lot of visual effects, is currently underway.

Rana has sent his best wishes to the movie's team.
