At the stately home, the band pick up playing after Sidney Young tumbles from the top of the stage's wooden framework. In the subsequent shot facing the band, the keyboard player lifts his right playing hand off the keys and, using his left hand, settles it in his lap just before the final keyboard chord is played.

In the rival magazine's article about Sophie Maes which Sidney is reading, the word "epitome" is spelt "epitomy."

At the party, Sophie Maes (Megan Fox) gathers her hair in her right hand, holds it above her shoulders and lowers herself into the pool. She walks through the pool in water that reaches just to her bust, and as she climbs out a clear "tide mark" is visible on her halter-neck dress, above which her shoulders and neck remain dry. In the next scene Sophie emerges from a lift with wet shoulders and neck.

When Sophie Maes (Megan Fox) is first introduced she claims to be a vegetarian and insists she would never wear fur, yet at the party near the end of the film she appears to be wearing what looks like a genuine fur stole. This is likely evidence of how film stars may compromise their principles once they become famous.

A printed interview with Sophie Maes reads "psychophants" rather than "sycophants".

When "La Dolce Vita" is screened in the park, no subtitles are provided — as the film is in Italian, it would be rather odd to show it to an English-speaking audience without any translation.

In the opening crane-down shot at the open-air party (approximately halfway through the film) you can spot a tiny "hair in the gate" at the bottom-centre of the frame. It remains in the following shot, but has evidently been removed by the time the next one appears.
