film. Interior filming at Wanamaker's took about three weeks, with shooting usually beginning around 9 pm and going until 6 am the next day. Additional scenes were filmed in the formal gardens behind The Hotel Hershey. Scenes taking place at the fictitious department store Illustra were filmed at the Boscov's department store in the former Camp Hill Mall (now Camp Hill Shopping Center) near Harrisburg, Pennsylvania. Philadelphia mayor Wilson Goode estimated the film injected $3 million into the city. Prior to the start of filming, Cattrall spent six weeks posing for a Santa Monica sculptor, who captured her likeness. Six mannequins, each with a different expression, were made. Cattrall recalled, "There's no way to play a mannequin except if you want to sit there as a dummy [...] I did a lot of body-building because I wanted to be as streamlined as possible. I wanted to match the mannequins as closely as I could." The actress also said that doing the film made her feel "grown up": I've become more of a leading lady instead of, like, the girl... All the other movies that I've done I played the girl, and the plot was around the guy. I've never had anybody to do special lighting for me, or find out what clothes look good on me, or what camera angles are best for me... In this movie, I learned a lot from it. It's almost like learning old Hollywood techniques... I've always been sort of a tomboy. I feel great being a girl, wearing a dress. Music Featured in the film, "Nothing's Gonna Stop Us Now" was a song co-written by Albert Hammond and Diane Warren and recorded by the American rock band Starship in 1986. It is a duet featuring Starship vocalists Grace Slick and Mickey Thomas. It reached number one on the Billboard Hot 100 on April 4, 1987, and topped the UK Singles Chart for four weeks the following month, becoming the UK's second-biggest-selling single of 1987. Reception Box office The film debuted at number three at the US box office behind Platoon and Outrageous Fortune, grossing $6 million over the four-day President's Day weekend, surpassing the other opener, Over the Top starring Sylvester Stallone, and exceeding box office projections. The film made a strong profit and grossed at least five times the budget for a total of $42.7 million in the United States and Canada. Critical
