It's a Great Feeling is a 1949 American Technicolor musical comedy film starring Doris Day, Jack Carson and Dennis Morgan in a parody of what goes on behind the scenes in Hollywood movie making.

Morgan, having lost all hope, discourages Judy from becoming an actress, but she is now determined to have her big break, explaining the hard work she has done to afford acting and singing lessons, as well as moving to Hollywood.

The screen test undergoes technical difficulties, which startles Trent when seeing it, and, coming on top of his "visions" of the same face everywhere (when Carson and Morgan planted Judy all around him), results in a nervous breakdown and a cancellation of production of Mademoiselle Fifi.

As a final attempt, Carson and Morgan conspire to disguise Judy as a famous French film star with dark hair named Yvonne Amour – and an inaccurate accent – but Trent still manages to recognize her despite the great amount of attention that "Yvonne" is receiving, including a meeting with Eleanor Parker and Patricia Neal and a performance of the song "At the Cafe Rendezvous".

Upset with all the backstage shenanigans she's been forced to endure, Judy considers returning home to Goerke's Corners to marry long-time sweetheart Jeffrey Bushdinkle.

Carson and Morgan consider stopping her, but Judy's friend Grace makes them realize that she will be much happier with her fiancé in a small town than an uncertain career in Hollywood, and they step back.

[4] The film resembled Day's early career as a waitress struggling to get into the pictures and nearly landing her big break when prepared to leave Hollywood.

He taught me dozens of tricks about how to move to precise camera marks without actually looking for them, how to handle myself in close-ups so that my face or profile rather than the back of my head would be in a shot, how to sustain the evenness of a performed scene.

"[8] In his book on Doris Day's career, author Tom Santopietro writes that the Crawford's self-parody of her "notoriously dramatic" screen image is the funniest bit in the film.

She automatically launches into a clichéd, melodramatic speech typical of her screen persona (in this case, from Mildred Pierce) and furiously slaps both Jack Carson and Dennis Morgan.
