Paxton, who played Watson’s father, had a small role in the movie, his last before his death at 61 after heart surgery in February.
“Bill was amazing,” Ponsoldt said.
“He was one of my favorite actors for the longest time, going back to when I was a kid.”
Ponsoldt said he had been looking forward to making more films with Paxton, who had also directed several movies during his career.
“I was excited to make more films with him. I was excited for him to make more films as an actor and a director.”
“The Circle” opens in theaters on Friday.
