First off, let me say that I believe Dame Maggie Smith to be the classiest actress in cinema. Her eyes are mesmerizing - she can look so coy and yet still patronize with a little curl in her grin. She certainly does not disappoint in this tale of comedic deception and romance.
The set-up is cute...Christopher Plummer plays Fitz Wynn, a truly talented but overly-satisfied stage actor who wants to star in a new movie written by his wife, Lily (Smith). Lily doesn't feel her Fitz is right for the part, and explains to him why and what she's looking for in the role. Fitz proceeds to orchestrate his own transformation (with the reluctant assistance of his agent) into Roberto Terranova, a blonde Italian who seems to be exactly what Lily wants. His deception seems successful, but does Lily want Roberto for more than just her movie?
It is at this point where the movie struggles - the initial delicious tension goes bland with redundancies; and although some wit is regained at the climax, the movie struggles through some sort of resolution, leaving us wondering just when the credits will roll?
Plummer does fine - his 'tantrums' seem contrived, but I don't really blame him. Smith is as witty as a lady can be with this material, which seems so dated now - especially the music (groan). As for the rest of the cast, Elke Sommer is totally wasted, and the remainders are unrecognizable and unimpressive.
In summary, the sole reason to watch *Lily in Love* is to watch Maggie Smith. She is graceful, she is radiant, and she is the perpetual professional. Rating 5/10 for the film :: 10/10 for Dame Maggie Smith
