Anchors Aweigh (1945)

In director George Sidney's and MGM's Technicolored, Best Picture-nominated, lightweight fluffy musical in the post-war years (with an Oscar-winning Best Musical Score), headlining a young and thin Frank Sinatra who crooned Julie Styne-Sammy Cahn tunes, and also featuring energetic Best Actor-nominated Gene Kelly (his sole Oscar nomination in his career) in a star-making role - it was the stars' first of three film pairings as a musical comedy team, and similar to Kelly's and Sinatra's later "sailor-buddy" film On the Town (1949):

• two sailors: experienced "Pomeranian sailor" and lothario - Gunner's Mate 2nd class Joseph "Joe" Brady (Gene Kelly) and the innocent, shy and naive Brooklynite - Seaman First Class Clarence Doolittle (Frank Sinatra), were on a 4-day shore leave from their ship Knoxville in San Diego, and the two traveled north to Los Angeles (Hollywood) looking for love connections
• they met up with straitlaced, widowed, aspiring opera singer Susan "Susie" Abbott (Kathryn Grayson) who worked as a film extra, and was befriending her young, orphaned, 9 year-old runaway nephew Donald Martin (Dean Stockwell in his film debut) who wished to join the Navy
• some of the tunes included Sinatra's Oscar-nominated "I Fall in Love Too Easily" and "What Makes the Sunset?", and Kelly's magical, extremely-effective and seamless, live-action magical dream dance with scene-stealing animated mouse Jerry, the character from MGM's "Tom and Jerry" cartoons, in "The King Who Couldn't Dance (The Worry Song)" number. Susan sang "Jalousie" (or "Jealousy") and "(All of a Sudden) My Heart Sings"
• the bashful Clarence fell hard for Susan, and Joe, who was chasing after actress/girlfriend Lola (never seen) at the time, helped him by promising to introduce Susan to her idol -- MGM music producer and famed maestro orchestra conductor José Iturbi (Himself) - without really knowing him
• however, a love triangle developed when Joe also began to have feelings for Susan (and she eventually did have an opportunity to audition with Iturbi), while Clarence met a more suitable down-to-earth, Brooklynite native match (Pamela Britton in her film debut, credited as Girl From Brooklyn and nicknamed "Brooklyn"), a friendly Olvera Street Mexican restaurant waitress
