The legendary filmmaker only has maintained sparse involvement with horror films here and there, and in such an event, it has always been a very family oriented tone. One prime example would be his involvement in the 1982 film Poltergeist, which he produced for Metro Goldwyn Mayer while at the same time directing E.T.: The Extra-Terrestrial for Universal Pictures. The film was so entrenched in Spielberg’s trademark style that many believed he secretly directed the film himself, as opposed to the low budget horror filmmaker credited with doing so in the film, Tobe Hooper.
Whatever the case may be, Spielberg wants such material he does to be in keeping with his cuddly non-offensive image at the box office (although he has indeed taken more risks with his more serious and personal films, such as Schindler’s List and Saving Private Ryan, both have won Oscars), and prefers to keep things light.
