The actor spoke to Ashanti Omkar, Bollywood expert for Cineworld and BBC London and BBC West Midlands radio stations, about his upcoming release.
"It is a soulful story about love. Whoever feels love, they should go and see it. It is extremely intriguing and riveting and you'll want to see what unfolds," he said.
"It is a nice take on love, as it showcases the ultimate obstacle that a lover has to overcome. It is a film that is a farewell to Yash Chopra and in my heart, the idea is that this film is a cut above the rest. It is historical."
Khan also shared memories of shooting in the UK from March to April and later in June.
"With London locales for Jab Tak Hai Jaan, I found the snow scene in Blackheath very pretty. There was a lovely restaurant called Everest Inn and the owner was really kind to us. They gave us warmth to sit in, and nice food," he said.
"The church there was a motif for the film. We had a small unit, and I've worked with many of them for 20 years, so it hardly seemed like a job to me."
Speaking immediately prior to the untimely death of director Yash Chopra, Khan said: "I don't know if I will do a love story again. I'm in love with an 80-year-old man. My love stories were not with the heroines, it was always Yash Ji.
"I would always say if I want a love story, I'll do it with Yash Ji. For me, he's the greatest lover in the world. Nobody does romance like him. He is pure at heart, and a clean filmmaker. I will miss him a lot."
Jab Tak Hai Jaan releases on November 13.
