The Upside true story reveals that the real-life paragliding accident happened in the Savoyard reliefs of Mont Bisanne in the Swiss Alps in 1993 when Philippe was 42. He had been distracted by thoughts of the workers he had laid off and hadn't been paying enough attention to what he was doing. As a result, he crashed.

Unlike Cranston, Hart did not fly in any of the scenes. As a result, filming Hart “paragliding” required some creativity, including a flying rig that hung from a crane, a shade structure simulating the glider's canopy, and a large fan for wind.

Philippe, the son of a French duke, became quadriplegic following a paragliding accident in 1993.

Julianna Margulies plays Lily, who has some romantic connection with Phillip. It's a small role, but Margulies is a major talent.
