Publicist: Michael Douglas Plans on Walking 'Wall Street' Red Carpet

Michael Douglas is determined to walk the red carpet at the NYC premiere of 'Wall Street: Money Never Sleeps' next Wednesday, marking his first public appearance since late August, when he stunned David Letterman with his healthy appearance following his first week of chemotherapy and radiation treatment for throat cancer, the actor's publicist tells PopEater.

The acting icon will be about halfway through an eight-week treatment program when 'Wall Street' premieres at the Ziegfeld Theater on Sept. 20. Publicist Allen Burry confirms that Douglas is making every effort to be there to mark the return of his most famous character, Gordon Gekko.

"That's the plan right now," Burry tells PopEater. "But we're literally going day-to-day as to know how much he can do."

"He would like to attend the premiere and show his support for the movie," Burry adds. "He knows that's part of the job and he's proud of the movie."

Radiation and chemotherapy take a major toll on a patient, and promoting a big film like 'Wall Street' can be grueling. The premiere falls roughly four weeks into Douglas' program and he plans to go to his regularly-scheduled treatment the morning of the event, just like he does five days a week.

During his visit to Letterman's 'Late Show,' Douglas said the treatment "knocks you out really hard" and that the "progression goes down" as the radiation and chemo intensify.

His publicist agrees.

"This all builds, and it's very hard to 100 percent predict," Burry says.

Despite the throat cancer diagnosis and the invasive medical intervention that followed soon after, Douglas has done his best to continue promoting 'Money Never Sleeps,' which co-stars Shia LaBeouf and Carey Mulligan.

Each stop on his scaled-back press tour has had a major impact, though -- from a cover interview with PEOPLE magazine to the Letterman appearance, which ended with the talk-show host passing on a rare hug of support.
