Eternal Sunshine of the Spotless Mind

Despite the fact that Charlie Kaufman's script and Michel Gondry's visual concepts were closely followed, the cast members were allowed many chances to improvise. Elijah Wood and Mark Ruffalo improvised extensively, and much of the dialogue between Jim Carrey and Kate Winslet resulted from videotaped rehearsal sessions, during which, the two became close by sharing tales of their real-life relationships and heartbreaks.

Many of the continuity errors listed here may well be deliberate. In the DVD extras, the movie makers explain that they played with the continuity to underline the struggle between the doctor and technicians trying to erase the memories and Joel trying to hold on to them.

The opening credits don't begin until about twenty minutes into the film and after much action and plot.
