Actor Varun Dhawan is "uncontrollably excited" about the remake of "Coolie No. 1", and says it is his new challenge. Varun will be stepping into the shoes of veteran Govinda, who featured in the 1995 film, which was directed by Varun's father David Dhawan. David is on board to helm the remake as well. Actress Sara Ali Khan will be filling in for Karishma Kapoor from the original.
