Hollywood director Paul Feig of "Ghostbusters" fame on Thursday said Bollywood superstar Shah Rukh Khan is a gift to the world.Feig, whose wife Laurie is an ardent fan of Shah Rukh and his work, on Wednesday shared a birthday message for the actor, on Twitter."Happiest of birthdays to you today, SRK! You are a gift to the world. Hope to see you soon, my friend," Feig, who has also helmed films like "The Heat" and "Spy", tweeted. Back in 2016, when Shah Rukh had hosted a star-studded dinner party for Apple CEO Tim Cook, Feig's wife had tweeted: "Some day I hope Paul Feig can be welcome at Mannat! Dream, Shah Rukh Khan."Shah Rukh had then invited the couple over for a meal. The director had then responded: "You're on, Shah Rukh Khan! I'll bring the ketchup. It would be an honour to meet you. Many thanks, my friend."
