Val Kilmer will never tire of discussing his onscreen kiss with Robert Downey Jr because it was such a "sweet and tender" moment.

The co-stars passionately lock lips in new movie Kiss Kiss, BANG BANG, and Kilmer insists he will cherish the embrace forever.

When asked if he is bored of discussing the controversial scene, Kilmer replied: "No, because he's such a good kisser! If it wasn't so sweet and tender, and if the light hadn't hit him in just that way and if the wind was blowing, then maybe."
