Gwyneth Paltrow ski collision trial updates and revelations.

Terry Sanderson, a retired optometrist, is expected to testify on Friday in his ongoing trial against Gwyneth Paltrow, who he claims crashed into him while skiing in 2016, causing lasting injuries and brain damage. Paltrow filed a countersuit claiming that Sanderson skied into her. The trial has been ongoing for seven years, and witnesses have testified about Sanderson's deteriorating health since the collision. Paltrow could take the stand on Friday if there is time. Sanderson is seeking more than $300,000 in damages, while Paltrow is seeking $1 in damages plus attorneys' fees.
