The ascent of Rajesh Khanna to superstardom in the early 1970s marked a significant shift in Bollywood, one that even seasoned stars like Shammi Kapoor felt profoundly. Shammi Kapoor, a dominant force in the 1960s with his energetic performances and iconic dance moves, found his popularity waning as Khanna's star began to rise. This transition wasn't just a change in leading men; it reflected evolving audience preferences and a shift in the very definition of a Bollywood hero.

Shammi Kapoor, often called the "rebel star", shaped the image of the stylish and charismatic Bombay hero. Films like Junglee (1961), China Town (1962), and Teesri Manzil (1966) showcased his unique dance style and established him as a box office draw. However, as the 1960s drew to a close, a new kind of hero emerged, one who resonated with audiences in a different way.

Rajesh Khanna, hailed as the "first superstar of Hindi cinema", brought a different kind of romance to the screen. Unlike Shammi Kapoor's "macho posturing," Khanna exuded a more gentle and courteous charm. His signature style, marked by a subtle head tilt, a crinkling of the eyes, and a captivating smile, made women swoon. Khanna understood the power of music, forming a successful collaboration with Kishore Kumar and R.D. Burman.

Between 1969 and 1971, Rajesh Khanna delivered an unprecedented 17 consecutive hits, a record that remains unbroken. Films like Aradhana, Kati Patang, Anand, and Haathi Mere Saathi cemented his place in Bollywood history and triggered the "Rajesh Khanna Mania". This phenomenal success led to the coining of the term "superstar" to describe his unparalleled popularity.

Actor Ashish Vidyarthi recounted an anecdote where Shammi Kapoor revealed how people mocked him about the dwindling crowds that once surrounded him. Kapoor wittily replied that the crowds had simply moved to "Aashirwad," Rajesh Khanna's bungalow, acknowledging the shift in popular adoration. This incident highlights the transient nature of fame and the industry's quickness to move on to the next big thing.

The change in audience preferences can be attributed to several factors. The themes that resonated with audiences in the '60s and '70s shifted from love, family, and identity to more complex narratives of struggle, war, truth, and justice. Rajesh Khanna's films often featured strong female protagonists and explored a variety of roles within the mainstream cinema framework.

Shammi Kapoor transitioned to supporting roles in the 1970s, appearing in films like Parvarish (1977) and Vidhaata (1982). Despite no longer being the leading man, he continued to leave his mark on the industry, even winning a Filmfare Award for Best Supporting Actor for Vidhaata. His last film appearance was in Rockstar (2011), alongside his grand-nephew Ranbir Kapoor.

The rise of Rajesh Khanna and the subsequent shift in audience attention serves as a reminder of the ever-changing landscape of Bollywood. While Shammi Kapoor's era was defined by energetic performances and a rebellious spirit, Rajesh Khanna ushered in an era of romantic charm and emotional depth. Both actors left an indelible mark on Indian cinema, but their contrasting styles reflect the evolving tastes of the movie-going public.
