I think you mean super 35. Titanic was also done this way. Gladiator is 2:35 widescreen but it was actually shot 1:85 and has been shown with the full image on an HD channel. The Fifth Element is also super 35 but only matted for the non special effect shots. The sfx parts had the regular pan & scan done. Harry Potter 1 & 2 had varying amounts of more vertical picture in the fullscreen versions but 3 actually lost a bit of vertical image in addition to about half on the sides. Not sure about 4.
