An interesting comment on Aliens color correction…
Anne Hurd: It’s a funny thing. Back then, Jim didn’t have color correction in his contract. When the first VHS [of Aliens] was made, the color timer decided it should be warm! We had dinner with [Rupert] Murdoch and they deep-sixed 250,000 VHS copies so Jim could color correct it.
