TWO icons of cult sci-fi comedy return to cinemas this week and they may encourage you to do the same.

Having first appeared on screens back in 1989, William S. Preston Esq and Theodore Logan - better known as Bill and Ted - are the nitwit, metal head time travellers whose music will one day dominate the 27th century.

In Bill & Ted Face the Music, they must save the universe.

Alex Winter and Keanu Reeves once again lead as Bill and Ted, respectively, with Hal Landon Jr and Amy Stoch back too in the parts of John and Missy Logan.

With George Carlin having passed away in 2008, his profit of the future - Rufus - is replaced here by Kristen Schaal’s Kelly. The daughter of Rufus and the Great Leader, Kelly comes named after Carlin’s own daughter. A touching tribute in a film full of heart.

Things aren’t looking so hot for Bill and Ted as the film opens. Their wives are unhappy and the world-saving song they’re supposed to be writing is sat well out of creative reach. It is at this low ebb that they learn that they have only until 7.17pm to write the song or all of reality will collapse.

Realising they haven’t a chance, Bill and Ted hatch a plan of the sort that only Bill and Ted could possibly think would work.

They’re going to travel forward in time and pinch the song from their future selves. And that’s just the start of the zippy plot and bonkers timeline that defines the film.

So crackers is Bill and Ted Face the Music that it very nearly didn’t happen. Though written as early as 2011, by series creators Chris Matheson and Ed Solomon, the film found no early traction with studios who couldn’t conceive of an audience worth the investment.

All that changed with the unexpected success of John Wick and the significant career boost it offered star Reeves. Success breeds success and the rest was history. Two John Wick sequels later and $25m has put Bill and Ted back in the picture.

Whereas the film’s American distributors - United Artists Releasing - pulled a big screen opening in favour of a Covid friendly online release, here in the UK, Warner Bros. have remained surprisingly brazen in sticking with cinemas alone. It’s certainly a risk.
