System for displaying an auxiliary image on a head-up display, the system including a panoramic projection screen, at least one panoramic projector for projecting a panoramic image on the panoramic projection screen, a beam combiner located between the panoramic projection screen and the audience, and an auxiliary projector for projecting the auxiliary image toward the beam combiner, the panoramic image being viewed by an audience. The beam combiner produces a combined image of the panoramic image and the auxiliary image, for the audience, by transmitting at least part of the panoramic image toward the audience, and by reflecting the auxiliary image toward the audience, such that the auxiliary image appears closer to the audience than the panoramic image.
