The Wrexham manager reckons having the Hollywood pair in the stands for a rare visit gave the occasion an added lift as the Dragons battled back at the weekend to secure a dramatic 2-2 draw with Watford at the Stok Cae Ras.
In front of Ryan Reynolds and Rob Mac — with Mac’s wife, actress Kaitlin Olson, also in attendance — Wrexham showed resilience and belief to avoid back-to-back Championship defeats.
Oliver Rathbone struck a stoppage-time equaliser to send the home crowd into raptures.
It means Wrexham’s draw tally is now into double figures, with 10 draws in their 21 games - more than any other club in the second tier.
The team are six points adrift of sixth-place, back in 14th spot in the table.
"I'm so pleased for the owners, who lift the whole place when they are here and I spoke to them briefly before the game," said Parkinson.
"There is a lot of positivity in the area with the new investment being announced and we've got to keep building on that and the spirit of the team was there for all to see today."

The point kept Wrexham firmly in the Championship play-off conversation, with the two sides separated by just a single point heading into the festive period.
It also ensured the Dragons responded after seeing their nine-game unbeaten run ended by Hull City in midweek.
Watford brushed aside Josh Windass' opener as first-half goals from Mamadou Doumbia and Othmane Maamma put the visitors on course for all three points.
But Rathbone's late intervention meant Wrexham avoided a second successive defeat.
Parkinson was delighted not just with the result, but with the man who delivered it — a player who has had to be patient after injury disrupted his season.
"I'm so pleased for Ollie Rathbone. He's had to wait to get his chance but he typifies everything we want here at Wrexham. His attitude is fantastic and he deserved that moment today.
"Ollie has played Championship football before and gave us the moment of calmness that we needed.
"We'd had a lot of good play and should have scored after the first goal, as we had some really good moments.
"But it was the split second of composure that Ollie has shown time-and-time-again that got us back in the game.
"The first goal knocked us, but we came out in the second half and responded well.
"When we were chasing the game like we were late on I thought we worked our way back into the game in a very controlled way."
Parkinson later expanded on Rathbone’s value to the squad, highlighting the midfielder’s patience and professionalism after an ankle injury suffered during pre-season in New Zealand and Australia.
"I'm so pleased for him," Parkinson said.
"Those of you here last year know what a key player he was, player of the year with some inspirational moments throughout the season.
"He got injured in pre-season, he's had to wait patiently for his chance, but he typifies everything we want here at Wrexham.
"He trains so hard every day, his attitude is fantastic and he deserved that moment today."
Watford, meanwhile, were left frustrated after letting victory slip. Assistant head coach Zigor Aranalde was particularly unhappy with the officiating late on.
"It's frustrating and the mistakes were there and the referee made a big mistake today and that has cost us.
"Everyone could see the free-kick he didn't give us which led to the second goal.
"It was a clear foul, one of the clearest I've seen this season, but the referee didn't give it and for me it's a big mistake.
"It's lucky for the referee that there is no VAR because that decision would be changed for sure. It's embarrassing what happened before Wrexham's second goal and that was the difference today.
"It's a shame, it's one point instead of three, but we've now only lost one in nine, so that is a positive."
