Varun pens a letter to dad

Filmmaker David Dhawan has turned a year older on Saturday and his son Varun Dhawan has penned a birthday wish for papa dearest on social media.

"Happy birthday papa. You are my No. 1 director," Varun wrote on Instagram along with a photograph that has him posing with David in Bangkok.

The father-son duo are currently shooting in Bangkok for the remake of the 1995 hit film, 'Coolie No.1.' David had directed the original, featuring Govinda in the starring role, to be reprised by Varun in the remake.

The original film also starred Karisma Kapoor, while the heroine in the new film is Sara Ali Khan.

In 2017, David directed a remake of his 1997 hit 'Judwa,' starring Salman Khan with son Varun.

Apart from 'Coolie No. 1,' David is known for helming hit films like 'Shola Aur Shabnam,' 'Bade Miyan Chote Miyan' and 'Mujhse Shaadi Karogi.'
