We got tired or at leastIgot tired of touring Australia, he recalls to EW with a laugh.

It went on for three years.

Because we stopped going on the road, we ended up withUp in Smokeinstead.

Australias loss would be the stoner comedy genres gain.

The plot ofUp in Smoke and there is one!

And therein lies your plot!

Well, one can only hope!

I dont want to claim any responsibility thats not there.

But both Cheech and I decided that the low-rider character and the stoner would be the main characters.

We just took it from there, and we kind of wrote as we went.

But for the most part, it was a good improvisational movie.

Luckily, we had hired actors that were improvisational actors and a crew that could adapt to quick changes.

Okay, after lunch were shooting this other scene, its not in the script.

Everyone didnt get freaked out.

Everybody was on the same page creatively.

The films cast also included Stacy Keach, who played the narcotics cop, Sergeant Stedenko.

His name wasAbe Snidanko.

He never did really forgive us.

Stacey Keach wasamazing, Marin says.

In the film, Man and Pedro are either high or looking to get that way.

You have to have concentration and energy over a long period of time, every day, he says.

If youre getting high every day, thats not going to happen.

Cheech and I were on the Paramount lot, he says.

And he said, You guys have no idea what youve done.

Thats my favorite memory.

That was the only time Warren Beatty ever really talked to us, because hes very, very quiet.

But he had to stop and give us his congratulations.

Oh, its wonderful, says Marin.

Its a big celebration of the recognition of pot, says Chong.

Its like we gave a Grammy to marijuana!
