A movie is never too old to warrant a sequel. For example, The Devil Wears Prada 2 will soon sashay its way into theaters 20 years after the original. The Meryl Streep-Anne Hathaway comedy is already one of the most highly anticipated movies of the summer. Going back further in time, the 1995 crime classic Heat has a sequel in development, with Leonardo DiCaprio and Austin Butler rumored to star.
