Walt Disney Co. has agreed to sell its Miramax film unit for $675 million to a consortium of investors, according to a media report late Thursday. TheWrap.com reported that Burbank, Calif.-based Disney (DIS 33.34, +0.20, +0.60%) agreed to sell the virtually defunct studio to Los Angeles billionaire Ronald Tutor and his partners, Morgan Creek studios, financial house Colony Capital and Hollywood mogul David Bergstein. The sale of Miramax is expected to come as a blow to Harvey and Bob Weinstein, who founded the studio and hoped to retain the 700-film library they compiled over the quarter-century that they ran Miramax.
