The two actresses teamed up onscreen for Jules Williamson's comedy "Off the Rails" and in an unearthed social media post from April, 2019, Kelly gushed about working with one of her heroes.
"Dream come true today shooting with Dame Judi Dench in London for @offtherailsfilms," Preston wrote beneath a photo of herself and her castmates, also including Jenny Seagrove and Peter Bowles.
"Goodbye London... goodbye Judi... Everyone who worked so hard on #offtherailsfilm I LOVED every moment of this film!" she added.
Kelly was also planning on reworking Ann Margret's role in "52 Pick-Up" with her high school pal Rod Lurie.
The director tweeted: "I knew #KellyPreston in high school. She was supernaturally beautiful and kind. Last time we spoke we discussed my directing a remake of 52-PICK UP in which she'd play the Ann-Margret role. It would've been special for us @PunahouSchool alums."
