The "Instant Family" star was out in Beverly Hills on Wednesday when he was asked about the legendary director's passing. Marshall gave Wahlberg his first movie role, playing Pvt. Tommy Lee Haywood in the 1994 comedy, "Renaissance Man."
After reflecting on what she did for him, Wahlberg said his thoughts turned to "the long list of how many people she helped, found, discovered, inspired ... took to another level. Not many people that had the kind of talent and the relationships and also the kind of person that she was."
He concluded by saying, "Love her. Miss her. She was best, she was one of a kind."
Penny Marshall passed away on Tuesday from complications related to diabetes. She was 75.
A statement from Marshall's family after her passing made note of her relationship with Mark Wahlberg, saying, "She even gave Mark Wahlberg his first acting job."
