Varun Dhawan was to work with father David Dhawan for the No 1 series, and this venture is all set to go on the floors soon. Reports suggest that the Dhawan duo will be working on an adaptation of Govind-starrer ‘Coolie No 1’. Varun is currently busy shooting for dance film ‘Street Dancer’, directed by choreographer-turned-director Remo D’Souza. The project kick started last month in Punjab and the team will soon be travelling to London for a 40-day schedule. However, the ‘Student of The Year’ star will be juggling the shoot between ‘Street Dancer’ and his untitled No 1 series film with father.
