Since the last American VistaVision picture, "One-Eyed Jacks" in 1961, the format has not been used as a primary imaging system for American feature films. However, VistaVision's high resolution made it attractive for some special effects work within some later feature films. Many VistaVision cameras were sold off internationally beginning in the early 1960s, which led to a significant number of VistaVision format productions (which did not use the trade name) in countries such as Italy and Japan from the 1960s to 1980s. The format was used infrequently for lesser-known Japanese films until at least 2000.
