“In 1985 I was married to Sylvester and this time I am the ex-wife,” says Nielsen. “But it was wonderful to have half of the cast there 32 years later. Who could have ever dreamed that you pick up the same roles many years after?”

She adds there was no drama between her and Stallone, calling the opportunity to work with him again “amazing.”

“We are two professionals and we kept it that way,” she says. “He stayed in the American corner and I stayed in the Russian corner. We were on opposite sides but it was pleasant.”
