Two-hero films was not a big deal or a topic of contention back in the 90s. Some of the superstars of today, were still trying to gain a foothold in the film-industry and a lot of them ended up working alongside in the same film. Aamir Khan has worked with Ajay Devgn in 'Ishq' and Salman Khan in 'Andaz Apna Apna'. At that time, Salman-Aamir, Shah Rukh-Salman, Akshay Kumar-Ajay Devgn, Aamir-Ajay used to do films together. Aamir, Ajay, Akshay, Salman are now the leading actors in Bollywood. Now their films clash together at the box office, two superstars usually avoid starring in a movie.
