Memes, ski etiquette and that missing GoPro video: Highlights from the Gwyneth Paltrow trial

When two skiers collided on a beginner run at an upscale Utah ski resort in 2016, no one could foresee that seven years later, the crash would become the subject of a closely watched celebrity trial.

When two skiers collided on a beginner run at an upscale Utah ski resort in 2016, no one could foresee that seven years later, the crash would become the subject of a closely watched celebrity trial.

But Gwyneth Paltrow's live-streamed trial over her collision with Terry Sanderson, a 76-year-old retired optometrist, in Park City has emerged as the biggest celebrity court case since actors Johnny Depp and Amber Heard faced off last year -- spawning memes, sparking debate about the burden of fame, and making ski etiquette rules of who was uphill and who had the right of way relevant beyond those who can afford resort chairlift tickets.

As attorneys prepared for closing arguments Thursday, here is a look back at highlights from the two-week trial:

For seven days, attorneys have highlighted -- and downplayed -- Paltrow and Sanderson's extravagant lifestyles.

Sanderson's attorneys are asking for more than US$300,000 in damages, but the money at stake for both sides pales in comparison to the typical legal costs of a multiyear lawsuit. Both sides have marshalled brigades of expert witnesses, including a biomechanical engineer and collision expert.

Paltrow's legal team has attempted to represent Sanderson as an angry, aging man who continued to travel internationally after the collision. They introduced photos into evidence of Sanderson camel riding in Morocco, trekking the Inca Trail to Machu Picchu in Peru, and taking a continent-wide loop through Europe with stops in the Netherlands, Germany, Switzerland, Italy, France and Belgium.

Sanderson's attorneys have questioned Paltrow about that day's $8,890 bill for private ski instructors for four children accompanying her, as well as her decision to leave the slope after the crash to get a massage. They've said the accident caused Sanderson to grow distant from friends and family, and they called his ex-girlfriend to testify about how their relationship deteriorated because he "had no joy left in his life."
