Around the 40 minute mark, when Juan calls Maria Jose on the telephone, she is wearing white gloves, then a second later, no gloves, then she is wearing the gloves for the rest of the scene.
A cameraman's hand is visible in the back seat when Maria Jose is alone in the car towards the end.
While Maria and Miguel walk along the side of the house at the wedding, a boom mic and a cameraman are reflected in the large windows along the wall.
Immediately after the wedding, the shadow of a cameraman is visible on the back of Juan's coat, as he enters the slum where the cyclist lived.
