Emily Blunt caught Tom Cruise off-guard when she kissed him during the filming of their new movie 'Edge of Tomorrow'.
The 31-year-old actress, who appears alongside Cruise in Warner Bros. futuristic sci-fi flick, said that she had to lip lock with the 51-year-old actor which he apparently wasn't expecting as he hadn't read the script properly.
She added that the actor was surprised by the act, and asked her if this was what they were supposed to do.
The film, which is based on the Japanese light novel 'All You Need Is Kill' by Hiroshi Sakurazaka, is set in the near future where the two actors play warriors who fight against aliens after earth has been taken over.
The movie will hit the Indian theatres on 6th June 2014.
