1. Leth must remake the film in Cuba (but with no set) with no shot longer than 12 frames, and he must answer the questions posed in the original film.
2. Leth must remake the film in the worst place in the world but not show that place onscreen; additionally, Leth must play the role of "the man". The meal must be included but the woman is not to be included. 
3. Because Leth failed to complete task 2 perfectly, Von Trier punishes him, telling him to either remake the film in any way he chooses, or redo obstruction 2 in Bombay again. 
4. Leth must remake the film as an animation. 
5. The fifth obstruction is that Von Trier has already made the fifth version, but it must be credited as Leth's, and Leth must read a voiceover narration ostensibly from his own perspective but in fact written by Von Trier.

Of course I remember it.
Women pretend things like that.
Yeah, what was I supposed to say?
That I remember the wine in the park, and...
us looking about the stars
fading away as the sun came up!
