A slightly more critical view was espoused by Penelope Mortimer in The Observer who said, "This nonsense makes quite a good film, well put together, competently photographed, on the whole sturdily performed. What it totally lacks is imagination." Box office According to Fox records, the film required $1.2 million in rentals to break even and made only $881,000 ($ in ).
