A mildly successful 2005 romantic comedy in which a troubled alcoholic (Mark Ruffalo) moves into an apartment with a less-than-solid woman (ReeseWitherspoon). He thinks she's dead. She insists she isn't. HilarityEnsues.
!!Contains the following tropes:
* AdaptationExpansion: The original novel ends with [[spoiler:Lauren (renamed Elizabeth for the film) waking up from the coma with no memory of her time as a ghost]]. The film added an extra scene where [[spoiler:Elizabeth and David meet again on the roof of the apartment, she remembers everything, and they kiss. Awww.]]
* AwLookTheyReallyDoLoveEachOther: Starts cropping up in the second half of the movie, especially in the second encounter with Darryl.
* BadLiar: David.
* BlindDate: How David and Elizabeth were ''supposed'' to meet.
* ConverseWithTheUnconscious: David appears to be doing this, but he's actually talking to Elizabeth's spirit. Also [[spoiler: Elizabeth's sister and nieces]].
* CuteGhostGirl: Elizabeth...or so she seems.
* DrowningMySorrows: David's whole ''life'' after his wife's death.
* TheFirstCutIsTheDeepest: David and his first wife.
* FlorenceNightingaleEffect: Not on David, but Elizabeth gets marriage proposals from one of her patients.
* HospitalHottie: Elizabeth, her mentor, and most of the rest of the staff.
* InnocentCohabitation: Perfectly chaste, as Elizabeth and David can't even touch if they wanted to. David even wears a swimsuit to shower in case Elizabeth pops up unexpectedly.
* ManicPixieDreamGirl: Elizabeth is a bit of an aversion, as she fulfills much the same role in the plot, but is actually the subdued and responsible force in David's life, in contrast to his wild friend Jack.
* MsFanservice: Katrina.
* TheMourningAfter: David, so hard.
* [[spoiler:NotQuiteDead]]: Elizabeth.
* NonhumanLoverReveal: In reverse (David knows she's a spirit before they actually fall in love).
* NowOrNeverKiss: The climax.
* ThePowerOfLove: Heavily implied to be the cause of the movie's events.
* TheReveal: Elizabeth is actually [[spoiler: in a coma]]. Also, Jack is [[spoiler: JJ, Elizabeth's sister's old beau]].
* TroubledButCute: David.
* TrueLovesKiss: How Elizabeth [[spoiler:wakes up from the coma]].
