A 30 Apr 2019 article by Barnana Sarkar of Meaww notes that Peter Davison provides the narration for a new Sundance TV adaptation of "The Name of the Rose". Excerpt:
"Similarly, Peter Davison's narration from the point of view of an old Adso, once again adds a nostalgic tinge to the periodical plot.".

(Note, Peter does not appear in the film, just provides the narration.)
