Keanu Reeves is pleased with how 'Bill & Ted 3' is coming along.

The actor is reprising his role as Ted Logan in the follow-up to 'Bill & Ted's Excellent Adventure' and 'Bill & Ted's Bogus Journey' and he says it's interesting to see how the duo are coping now they're middle-aged men rather than carefree teenagers.

Keanu - who will once again star alongside Alex Winter - said: ''We have a nice story. We'll see if anyone else wants to make it.''

The star was then asked about the various challenges of imagining Bill and Ted as middle-aged men and replied: ''One of the plot points is that these two people have been crushed by the responsibility of having to write the greatest song ever written and to change the world. And they haven't done it. So everybody is kind of like: 'Where is the song?' ''

Although he didn't reveal too much about the storyline, Keanu, 47, admits the pair have lost some of their sparkle from the first two films and it needs finding again.

He told GQ: ''The guys have just drifted off into esoterica and lost their rock. And we go on this expedition, go into the future to find out if we wrote the song, and one future 'us' refuses to tell us, and another future 'us' blames us for their lives because we didn't write the song, so they're living this terrible life. In one version we're in jail; in another we're at some kind of highway motel and they hate us.''
