Bachchan Junior posted a picture of a vehicle with "Nandu" written on it in Hindi. "Nandu" was the "Guru" actor's character name in "Happy New Year", which also starred Boman Irani, Sonu Sood and Jackie Shroff.
The 43-year-old actor captioned the image: "It's a sign! SRK, Deepika Padukone, Farah Khan, Boman Irani, Sonu Sood and Jackie Shroff. Time to get the band back together guys."
"Happy New Year" told the story of a heist at a hotel in Dubai.
Abhishek Bachchan was last seen on screen in "Manmarziyaan", which also featured Taapsee Pannu and Vicky Kaushal.
