The Wall Street star was among the guests in the audience at New York City's Palace Theatre as Glenn reprised her role as Norma Desmond for the show revival, and he headed backstage after the final curtain call to catch up with his longtime pal.

Michael and Glenn hugged and smiled for the cameras as he congratulated the 69-year-old on her performance.

The actors have remained close ever since becoming friends while playing lovers in twisted 1987 thriller Fatal Attraction, and last year (16), Michael, 72, spoke fondly of their time together both on and off set.

"Glenn and I did a little movie in (the 1980s) which stood a lot of people on their heads, called Fatal Attraction," he recalled at the 2016 AARP Awards luncheon. "It was a brave film, it's part of the memory of those films that keeps us all together and our friendships (thriving)."

Glenn made her West End debut last year (16) in a sold out London run of the Sunset Boulevard revival, based on Billy Wilder's 1950 film, and the limited Broadway engagement launched earlier this month (Feb17).

The role of Norma Desmond is one Glenn is very familiar with - she originally tackled the part in a 1994 Broadway production of Andrew Lloyd Webber's popular musical, which earned her a Tony Award in 1995. The play also picked up an additional six Tonys, including Best Musical.
