While in conversation with the U.K.‘sThe Timeslast year, Mirren explained that her working relationship with Ford differed from when they first worked together in 1986.
“The relationship was obviously very, very different then because Harrison was already an enormous movie star and I was a theatre actress out of London andnobody had heard of me,” she said.
“Now our relationship is very different because I’ve sort of caught up with him,” theAcademy Awardwinner added to the publication. “Well, I’ll never catch up with him completely but I’m a little bit closer than I was.”
