Two would-be rockers from San Dimas, California, were once told they'd save the universe during a time-traveling adventure, but find themselves as middle-aged dads still trying to crank out a hit song and fulfill their destiny. This is the third installment of the Bill & Ted series, which began with Bill & Ted's Excellent Adventure in 1989. The film lingered in development for a number of years, with the script initially being worked on in 2010. The project didn't really start to gain steam until 2018 when stars Keanu Reeves and Alex Winter were confirmed to reprise their iconic characters.
