The actor revealed that he was unable to attend the Feb. 22 Academy Awards in Los Angeles, which featured a special appearance from "Sound of Music" star Julie Andrews; however, he also noted that he felt that the night truly belonged to his on-screen co-star.
"I didn't go to the Oscars because first of all I couldn't, and the second thing, it was a tribute to [Julie Andrews]," Plummer said. "I would've looked stupid being there and not doing anything."
Plummer also had praise for Gaga, who performed a "Sound of Music" medley that included "Favorite Things," "Edelweiss," "Climb Ev'ry Mountain" and the title song. "...Lady Gaga was, I thought she was just wonderful. She sang it so well in the style of the piece and she didn't add any modern rock sounds. She did it straight and she has a lovely voice."
Andrews and Plummer do have plans to reunite in Hollywood March 26 for the opening night of the 2015 TCM Classic Film Festival, featuring a newly restored screening of "The Sound of Music." Robert Osborne will host a Q&A with the film's stars prior to the screening.
