The intense cold and heavy snowfall in Shimla has taken its toll on superstar Amitabh Bachchan, who is down with fever and a sore throat here.

But the actor continues to shoot for Shoojit Sircar's Shoe Bite, with frequent breaks to rest. The Big B fell ill on the sets late Friday.

Sarika stars opposite Amitabh in the film, an autumnal love story set in Shimla. The other members of the cast include Diya Mirza and Jimmy Shergill.

Since shooting began over two weeks ago, the resort town has been experiencing a severe cold spell accompanied by spells of snowfall.
