What did Dev Anand have in common with Gregory Peck ?
Dev Anand and Suraiya met Peck for the first time at Mumbai's Willingdon Club, after the Filmfare Awards in 1954.
Did they work together after that ?
He knew of the "Indian Star" as an actor, more so probably because his romance with Suraiya was grabbing the headlines, and they had a chat.
Did they become friend ?
The second time they met was in Rome when Dev Anand was on his way back from the Venice Film Festival, he visited him on the set of Roman Holiday.
