Akshay Kumar finds it "sad" that actors these days are reluctant to sign films having two or more heroes, and instead opt only for films that offer them solo-hero subjects.

"To be honest and without taking names, actors in our industry still don't understand the fact that they should do two-hero or three-hero subject. They are not doing it. I have tried to find out why they don't want to do it. Everybody wants to do a solo hero subject. The earlier generation - my generation - did it. They even worked in three-hero subjects," Akshay said at a promotional event for his new film, "Mission Mangal" on Friday.
