“Speaking for myself, you know, I tried [modifying a film] once and I lived to regret it. Not because of fan outrage, but simply because I was disappointed in myself. I was overly sensitive to some of the criticism ET got from parent groups when it was first released in '82 having to do with Eliot saying "Penis Breath" or the guns...and then there were certain brilliant, but rough around the edges close ups of ET that I always felt, if technology ever evolves to the point where I can do some facial enhancement for ET, I'd like to. So I did an ET pass for like the third release of the movie and it was okay for a while, but then I realized that what I had done was I had robbed the people who loved ET of their memories of ET. And I regretted that.”
