Actress Kajol said 'Dilwale Dulhania Le Jayenge' is the "longest-running film in the world right now" and will continue to break its own record every year. "I think the part about DDLJ, Kuch Kuch Hota Hai, and all these films is that when you watch them they're real even today," she added. DDLJ recently completed 29 years of release.
