Brett Ratner and Hrithik to collaborate again?

Ratner had edited the English version of the film starring Roshan and Mexican actress Barbara Mori, and since then they share a strong friendship.

Roshan recently saw Ratner's Tower Heist and was left impressed. He took to micro-blogging site Twitter to congratulate the filmmaker.

"Brett Ratner long time! Just watched Tower Heist! Super film! Brilliantly directed! You are the man Brett! hope all is well...Cheers my friend," the 38-year-old tweeted.

To that, the 43-year-old filmmaker replied: "Hrithik thank you... I heard you are in the biggest hit in India. Can't wait to see it... Working on a big idea for us to collaborate."
