Early in 1990, Megadeth joined Slayer, Testament, and Suicidal Tendencies for the successful European Clash of the Titans tour, featuring several American thrash metal bands. An American leg began the following year featuring Megadeth, Slayer, and Anthrax, with Alice in Chains as a supporting act. The tour was considered a multi-headliner, as the three main bands alternated time slots. In addition to the Clash of the Titans tour, Megadeth (along with Testament) supported Judas Priest on their "Painkiller" tour in North America late in 1990 and appeared at the second Rock in Rio festival in January 1991. In July 1991 the song "Go to Hell" was featured in the film "Bill & Ted's Bogus Journey" and on its soundtrack.
