Imagine Me & You

A fairly standard but very sweet and heartwarming Romantic Comedy about a newlywed who finds herself falling in love with someone else - the lonely woman who arranged the wedding flowers. As she's walking down the aisle to her husband-to-be.

The film stars Piper Perabo as Rachel, Lena Headey as Luce, Matthew Goode as Heck, and Anthony Head as Rachel's father Ned.

Tropes used in Imagine Me & You include:

Almost Kiss: Interrupted by a passing car.
Breaking the Fourth Wall - Heck may have done this at the very end when he looks at the camera and smiles.
The Casanova - Cooper.
Chekhov's Skill - When Luce teaches Rachel how to project your voice, and later Rachel uses this to find Luce. It's really quite romantic. It's a shame if you've read this and not seen the movie yet.
Cloudcuckoolander - Ned.
Converse with the Unconscious: Well more accurately speaking with the plastered.
Covers Always Lie: The wedding dress Rachel is wearing on the cover is not the same as the one she wears in the movie.
Daydream Surprise - Rachel, in H's classroom with Luce.
Foreshadowing - Used quite a lot, and very well at that.
- A woman comes into the flower show and breaks down crying because she is pregnant and her boyfriend doesn't know. Later, during the end credits we see Cooper walking around with a baby.
- Heck mentions early in the film that he wants to write a book about partying around the world. Later Heck does just that.
- Luce puts the missing ring on Rachel's finger.
Flower Motifs - Pretty much inevitable, in a Rom Com starring a florist, but most important is Rachel's favorite, the lily, which Luce translates as "I dare you to love me".
- Also consider the origin of the term "Yuri" in the context of the film.
Girls Love
Hands-On Approach - When Luce teaches Rachel how to project her voice.
Happy Ending - Even Heck gets one, despite his wife leaving him.
I Want My Beloved to Be Happy - Explored rather deeply as a central theme of the film.
Lipstick Lesbian: Luce, Rachel (eventually).
Lost Wedding Ring
Love At First Sight - Essentially the premise behind the romance in the whole movie.
Love Triangle - More accurately a 3rd wheel.
No Bisexuals: It is implied that Rachel was never truly attracted to Heck.

You are my best friend. That was enough before, and it will be enough again.

One-Scene Wonder - Angel Coulby gets an adorable one in the final scenes of movie as part of the aforementioned Happy Ending for Heck.
Orbital Kiss
Race For Your Love
Shout-Out - Some of the questions asked by H are the titles of books from the Imponderables series: When Do Fish Sleep? and Do Penguins Have Knees?
"Shut Up" Kiss - More of a one sided variation of this by Rachel. She basically kisses Luce to shut herself up.
Wise Beyond Their Years - H.
