The film, reportedly titled "The Ring", marks the first collaboration between the 50-year-old "Fan" star and Imtiaz.
Shah Rukh is said to be playing a tourist guide in the movie. The actor posted on Instagram a video of a museum in Prague, which he captioned, "Pretty in Prague."
A video from the film's set, shared by a fan online, shows Shah Rukh walking up to a parapet with a large brown bag strung around his shoulder, while waving a red flag in order to attract attention from the crowd.
The film also marks SRK's return to an out-and-out romantic film after four years. His last on screen love story was late director Yash Chopra's "Jab Tak Hai Jaan".
Hence, his fans are excited about the movie, more so because he has teamed up with Imtiaz, who is known for his penchant for contemporary romances.
