Released in July 1992 , '' Countdown to Extinction '' entered the '' Billboard '' 200 chart at number two and was certified triple platinum in the United States . The album 's overseas success helped the band to develop a larger following outside the US . It received a nomination for Best Metal Performance at the 1993 Grammy Awards , and its title track won a Genesis Award from the Humane Society in 1993 for raising awareness for animal rights issues . Ellefson later said that he and Friedman were disappointed that Megadeth did not win the Grammy : " It was such a bizarre moment , because it was as if the amount of work it had taken to ramp up to that hopeful night was literally gone in a second . " A world tour in support of the album was launched in late 1992 , with Pantera and White Zombie as supporting acts . The tour included a North American leg in early 1993 , with Stone Temple Pilots as the opening act . One month into the leg , the remaining shows , including dates in Japan , were canceled when Mustaine returned to substance abuse , ending up in a hospital emergency room . After seven weeks in rehab , Mustaine emerged sober again and the band returned to the studio to record " Angry Again " . The song is featured on the soundtrack of the 1993 film '' Last Action Hero '' and received a Grammy nomination in 1994
