Our "sunday spotlight" shines today on two acting LEGENDS, ian McKellen and patrick stewart, both knighted by the queen. For their contribution to theater. They're starring in two new shows on broadway. American audiences may know them as enemies in the x-men franchises, abc's john donvan found them the best of friends. Sflr it's the hats that throw you off. These two guys, they're out of costume. But zoom in on this one, costume, please, and yep, THAT'S'ian McKellen playing hobbit. The other guy, zoom please, in costume, yep, patrick stewart, back when he was playing john on "star trek." The other guy, that's me, truly in awe to be out on the streets with these two guys. What's cool is what these two guys have been doing up on twitter, getting around new york city, here and here, and even down here on the day the trash was put out or maybe it was the day after, just two brit bros doing new york city. We stopped here and held up traffic. Jumped out and took the photo with the trash bags. People were still thinking, who are those guys? Recognize those guys. We are shameless self-publicists. But what's nice on this occasion is that, we're in charge of ourselves. That's why we're doing these two plays. Reporter: These two plays, that's the point, because right now the two actors are in two broadway shows together. "Waiting for godot" and "no man's land." The photos, they're in character here. They're doing the two characters from "waiting for godot." It's a bit of a publicity stunt. They're having fun doing it. This broadway dream team who have been friends for a long, long time. Being friends with the people that you work with I think is pretty important. We have shared experiences working at the national theater. Reporter: At the same time? At the same time, but never in the same place. Never in the same place. Reporter: But back at the VERY START, IN THE 1960s, McKELLEN GOT BIG BEFORE STEWART Got big. I was working with regional theater, he was working in the national theater, he was in the west end. Somewhere that I can only fantasize about. So, I was a fan to begin with and I carry a little of that with me still. Only a little. We need you to hope again. Reporter: Of course, they were both global stars and friends by the time they made "x-men" together and now they're working night after night in new york, the other important thing they have in common is knowing how it feels to be working so hard at their age, 73 for STEWART, 74 for McKellen in previews, they shared a dressing room. What do you guys get up to in the dressing room? We both sleep a great deal. The bed is the most important piece of furniture. Reporter: And you really mean that, don't you? Oh, absolutely. It's very nice to not be the only old man in the play. If they're hurting it doesn't show. Two great pros. Two great bros. Two guys in hats on the sidewalks of new york. For "this week," I'm john donvan, abc news, new york. Our thanks to john for that. Now, we honor our fellow americans who serve and sacrifice. This week, the pentagon released the names of six soldiers killed in afghanistan. And that's all for us today. Thanks for sharing part of your sunday with us.
