Whoopi Goldberg just finished her one-woman show and is now busy preparing for her upcoming live HBO Comedy Hour on August 6th. Yet the funny woman still does not consider herself a comic. I wish I could do stand-up, you know. I wish I could go out and tell jokes and do punch lines and stuff. But I get so wrapped up in telling the joke that the punch line sort of dies. Two box office biggies who are delivering punch lines are Tom Hanks and Sally Field. That's the name of their new movie, but both are quick to say that life as a stand-up comic is no joke. A stand-up is very frightening. You're up there all alone. It's also extremely lonely. There's nobody to talk to. You talk to the audience and if they talk back, chances are they're heckling you. It's a new show and just wrapped production and will have audiences laughing this fall. Gregory Hines, better known for his acting and tapping abilities, is singing a different tune. He's just released his debut album produced by Luther Vandross. It was a great experience working with Luther and just recording an album. You know, every line of every song was an education for me. And teeing off as a pro golfer in the HBO picture Dead Solid Perfect is Randy Quaid. But Randy explains his real reason for putting around on this screen. It's a joy to come to work and be able to hit golf shots. I'm Jim Caldwell for HBO Entertainment News. It's almost time for the HBO Comedy Hour from the Montreal International Comedy Festival. Oops, sorry. I'd like to present you now a collection of the craziest things here in all of Montreal. Come on, this way. Walk this way. Hello, girls. Catch the HBO Comedy Hour live from Montreal with host John Candy this Saturday, 10 Eastern, 9 Central. You're out of here. No Mercy stars Richard Gere as the Chicago cop looking to solve his partner's murder and Kim Basinger as the mysterious woman from the bayou who leads him to his prey. You don't know me. You don't know anything about my life. You think you know everything, but you don't know anything about my life. I do know one thing. Joy Collins is dead because of you. And you stood there and you just watched, didn't you? Didn't you? Didn't you? You don't know what I've seen in my life. Do you think that was the worst? Come on. Making movies is always a test of endurance, but in the case of No Mercy, it also required steel nerves and a strong stomach. Was horrifying. And Richard and I were in the swamp ourselves up to here. It was a very environmental film. I think National Geographic should have come down there and shot us. We had to have tetanus and all those other shots. And it was just, I can't even tell you the truth, really. I mean, this just is the surface of the iceberg as far as the real truth as to the physical torment we went through for this film. Much of the action of No Mercy takes place in the Louisiana swamps. We had alligators around. We had water moccasins. We had, but thank God it was in the wintertime because most of them were sleeping. We got halfway through this thing and something wrapped itself around my leg under water and wouldn't let go. Kim didn't like any of this stuff. Like anything to do with the oaky things, she didn't want any of that. All of a sudden little alligators start popping out everywhere and mother alligators and father alligators and snakes and God only knows what. If you don't believe me, you don't matter. Wrong. I matter a whole lot, lady. We're going to jail. My boyfriend's going to stop breathing. I was having dinner at a restaurant there and a guy was asking me what I thought we were shooting. I described the pylons and the pier by the, and he said, yeah, and how many riflemen did you have with you? I said, none. Well, I said, that's alligator pit. I said, they got, they got 20, 30 big and it's been there. We have a scene in the movie where we, we crashed. Richard's driving a car and I am handcuffed to Richard and we are under the water, buddy breathing while handcuffed to each other and having to escape in a car. And if you don't think panic and we had it all worked out like a ballet where it would fall forward in the water and like I was knocked out and things like this, I'm telling you, it was horrifying. So we, I, I went through it on that film. We spent about four or five nights shooting this and we could last maybe 10, 15 minutes in the water and they had to pull us out. We just frozen up. He's gone, man. He's gone. Michelle. Michelle, where are you? I don't know where to go. I think. So why put themselves through such tests of endurance? Everything's easier when you're actually there. You don't have to pretend you're in the water. You know, you walk through the water and actually sloshes and your clothes get wet and they get heavy and you react that way. You know, it's always easier to do it in a real place. My God. I mean, you act quite differently when there are wild things trying to get into your wetsuit. I mean, it's easy to jump into those scenes. They're all, you know, uh, life endangered situations. You react spontaneously to them. And you know, I always do my own stuff. So I mean, someone's coming at you with a knife, you react. Those are the easiest things to do. They're totally real. There's nothing fabricated about it. This month on HBO. The first casualty of war is innocence. Now the first real movie about the war in Vietnam comes to HBO. Winner of the 1986 Academy Award for Best Picture, Oliver Stone's Platoon, coming in September.
