The film is coming up on its 15th anniversary, and ET's Carly Steel got to chat with Hudson and Hawn about the movie while at Stella McCartney's women and men's Autumn-Winter 2018 collection launch in Los Angeles on Tuesday.
"I was very involved in [the development stages]," Hudson recalled. "So, to watch a movie I was so involved in from the very beginning and see the success, [it] was awesome."
Hawn, 72, chimed in to share her own memory that she has of McConaughey at that time. "You know what was so great about it ...while you (Hudson) were making it, and Matthew was baying at the moon," she reminisced. "It was one of the great nights."
Hudson added, "We were shooting in Toronto and we went out and had a little weekend with all our friends and the baying at the moon was a great moment."
Further praising her 38-year-old daughter, Hawn gushed, "It was so great and that's why it was such a great movie -- because it had such great chemistry. You were so great in it, honey."
The mother-daughter duo also teased Paul McCartney's appearance at the event, with Hudson later sharing an Instagram video of his performance. "Front row with... our parents," she captioned the video of McCartney's daughter dancing with Hawn.
