 Despite his slim appearance as a young man, Elvis had been a talented amateur boxer in his youth and even represented his school. This skill would come in handy during his film career where he was frequently required to get involved in a brawl. Elvis' mother, Gladys Pressley, died aged 46 in 1958. Although not seen in the film, Vernon Pressley, Elvis' father, remarried in 1960. Vernon died of a heart attack in June 1979 at the age of 63, less than two years after his son. The film had a 12 minute standing ovation at the Cannes Film Festival after the screening was over. Although it's never alluded to in the film, Elvis was actually a huge fan of technology and was one of the first people in the US to have an analog cell phone installed into his car and had one of the first Betamax video tape recorders in his home after they were introduced by Sony in 1975.
