Dilip Kumar and Raj Kapoor, two iconic figures in the Indian film industry, had a close friendship that dated back to their childhood in Peshawar. Despite their bond, they only collaborated once in their careers, in Mehboob Khan's film 'Andaz.' They discussed another project, initially titled 'Gharonda,' which later became 'Sangam.' However, Dilip Kumar set a condition for Raj Kapoor, asking him to choose between acting or directing the film. This request hurt Kapoor, who felt it undermined his vision for the project. Shammi Kapoor, Raj's brother, confirmed that Raj was deeply affected by this condition, stating that it felt like asking him to step away from his own creation. Eventually, 'Sangam' was made with a different cast and released in 1964, featuring a love triangle involving Raj Kapoor, Vyjayanthimala, and Rajendra Kumar. Additionally, rumors of an affair between Raj Kapoor and Vyjayanthimala surfaced during the film's production, although Vyjayanthimala later denied these claims, suggesting they were fabricated for publicity.
