You can get an anamorphic lens, and a video scaler. The scaler is placed before the projector to remove black bars from 2.35 films and scale them up to fill the full display chip in the projector. This is called vertical stretch. The anamorphic lens then does a horizontal stretch optically to fill the screen.

These two items together will probably cost as much as a new projector which does all of this internally.
