1 Vinod Khanna and Akshaye Khanna
The senior Khanna produced Himalay Putra (1997) to launch his second son Akshaye. Though it had a satisfactory opening, the film failed to make the cut. Vinod played Akshaye's father, estranged from his wife played by Hema Malini. A teenage love story, the film had newcomer Anjala Zaveri as the female lead.
2 Dharmendra and Sunny Deol
The pair has been together in numerous, but mostly forgettable films of the comedy genre, at least three of which also featured Sunny's younger brother Bobby. Yamla Pagla Deewana (2011), its sequel Yamla Pagla Deewana 2 (2013), Saveray Wali Gaadi (1986), Sunny (1984), Vardi (1989), Kshatriya (1993), Sultanat (1988), Phoolan Hasina Ramkali (1993) and Kaise Kahoon Ke...Pyaar Hai (2003) were among them. In 2007, however, Apne went on to become a hit.
3 Rajendra Kumar and Kumar Gaurav
Late Rajendra Kumar, a successful 60s star himself, launched his son Kumar Gaurav aka Manoj Tuli with his production Love Story (1981). The film went on to become a blockbuster, making Kumar Gaurav an overnight sensation. The pair featured together again in Star (1982) where Rajendra had a guest appearance, and Phool (1993). None of them came even close to the success of Love Story.
4 Feroze and Fardeen Khan
The pair shared the screen five years after Fardeen was launched in Prem Aggan (1998). Janasheen (2003) didn't feature them as father-son, but had Feroze play a negative role. The film was released on the same day as Shah Rukh Khan's Kal Ho Na Ho and failed at the box office. Two years later, the duo appeared together in Ek Khiladi Ek Haseena (2005) in which Fardeen played a con-man. This film too did average business.
5 Sunil and Sanjay Dutt
The two shared some poignant scenes in the national award winning Munna Bhai M.B.B.S. (2003) in which Sanjay plays a goon who fakes his identity as a doctor to please his father, played by late Sunil Dutt. Though the two had appeared in other films in the past - Reshma aur Shera (1971), Rocky (1981) and Kshatriya (1993) with Sanjay cast as a child actor – Munna Bhai M.B.B.S. was the first film they shared the screen in.
6 Prithviraj, with Raj and Shammi Kapoor
The Kapoor family has given Indian cinema a number of stars as well as reel-life pairings from within the clan. Prithviraj and Raj appeared in the acclaimed Awara (1951) as an estranged father-son pair. Prithiviraj followed it up with Pyaar Kiya To Darna Kya (1963) and Jaanwar (1965) with Shammi Kapoor. Not to forget the iconic Kal Aaj aur Kal (1971) that featured not just one but two father-son pairs; Prithviraj, Raj and Randhir Kapoor represented three generations in the film that tackled ideological clash. It also had Randhir's real life wife Babita cast opposite him.
7 Raj, with sons Rishi and Randhir Kapoor
Only 18 then, Rishi played a young Raj Kapoor in Mera Naam Joker (1970). His debut won him a national award. Raj and Randhir appeared as father-son in Dharam Karam (1975).
8 Rishi and Ranbir Kapoor
The two featured in the film Besharam (2013), which created a flutter for casting not just the real-life father so duo but also Rishi's wife and former superstar Neetu Singh. However, the film tanked, with Rishi admitting in an interview later than he and Neetu were sorry for doing the film.
9 Amitabh and Abhishek Bachchan
They first appeared together in Bunty aur Babli (2005) that had Rani Mukherjee cast opposite Abhishek. However, it was the chemistry between Aishwarya Rai and Amitabh (in an item song) that drew far more attention than the father-son pairing. Amitabh and Abhishek have since worked together several times including in Paa (2009) where, unconventionally, Abhishek played Amitabh's father. Other films include Sarkar (2005), its sequel Sarkar Raj (2008), Ek Ajnabee (2009) where Abhishek had a guest appearance, and Kabhi Alvida Naa Kehna (2006).
