Answer 1

As of 2013, worldwide gross is $38,869,464 at box office ticket sales. (this includes the original release and several fan events and charity re-releases). It cost $39 million to make (plus a $10 million advertising budget)

It's made considerably more in DVD and Blu-Ray rentals and sales than it ever did at the box office, however the official numbers have not been made public. Industry experts estimate DVD, Blu-Ray and television rebroadcast rights have brought in at least between 60 and 100 million dollars in addition to the box office gross. The estimate is based on how long it spent on various best seller/rental lists in comparison to other films with known sales figures at the time.
