PARK CITY, Utah — The retired optometrist suing Gwyneth Paltrow over a ski accident he claims left him with permanent brain damage emailed his daughters the day of the crash to say: “I’m famous,” the actress’s attorney said in his opening statement Tuesday.

Dr. Terry Sanderson, 69, sent the missive just hours after he claims Paltrow, 50, ran into him on a ski slope at Deer Valley Resort on Feb. 26, 2016, and fled the scene, her attorney, Steve Owens, told jurors in Park City, Utah court.

Sanderson’s daughter replied that she couldn’t believe “‘[the crash] was caught on GoPro,’” Owens said. The alleged GoPro footage of the crash, the attorney pointed out, has never been recovered.

Sanderson, Owens said on the first day of trial, became “obsessed” with suing Paltrow after he realized she was a famous actress.

The former Army eye doctor is seeking $300,000 in damages from Paltrow in his suit accusing her of negligence. The Oscar-winning actress countersued, but is requesting a paltry $1 in damages and for the plaintiff to pay her legal fees.

Paltrow’s version of events — that Sanderson was the one who allegedly crashed into her — will be supported by testimony from her teenage children, Apple and Moses Martin, and her now-husband, Brad Falchuk, the attorney said.

“This is not a hit-and-run,” the Salt Lake City-based attorney told the court of the accident, which Sanderson claims left him with broken ribs and a concussion that led to permanent brain damage.

Apple, 18, and Moses, 16, did not witness the crash, but were on the ski slopes with their mother and several ski instructors when the accident took place, Owens said.

Falchuk, who was dating the “Goop” founder at the time, was also present.

Sources close to Paltrow previously told The Post that the Hollywood heavyweight will take the stand in her own defense.

During his opening statement, Owens also slammed allegations made earlier Tuesday by Sanderson’s attorney that the “reckless” and “distracted” star left the scene of the collision as “offensive” and “utter BS.”

Owens claimed that Sanderson had a history of neurological problems, and discouraged the jury from reaching a verdict based on sympathy for the plaintiff’s condition.

To drive his point home, Owens opened and concluded his statements by showing the courtroom an image of Lady Justice, the allegorical figure pictured blindfolded while holding scales.

Paltrow, who appeared in court on Tuesday, sat mostly expressionless while Owens spoke. When entering and exiting the courtroom, the famous blonde blocked her face with a blue notebook.
