Neil Patrick Harris and Oscar Isaac both took to social media to mourn Fisher and Reynolds with emotional posts, expressing their admiration for the actresses they had previously worked with.
Isaac, who starred alongside the Star Wars icon in 2015's The Force Awakens, remembered the 60-year-old for her sharp wit in poignant Facebook posts — in which he shared a photo of Fisher and Mark Hamill on set.
The 39-year-old also shared a photo of Fisher's beloved dogGary, writing:
On Saturday, Todd Fisher, and his wife, Catherine Hickland, organized a public memorial service for his sister, Carrie Fisher, and mom, Debbie Reynolds, who died just a day apart back in December.
The beautiful service was held at Forest Lawn Memorial Park in Hollywood Hills, and was live-streamed on Reynolds' website for all to experience.
Celebs, fans, and animals alike gathered to celebrate the lives of the legendary actresses with an event that featured a tribute song from James Blunt, a performance from the Gay Men's Chorus of Los Angeles, a dance tribute from the Debbie Reynolds dance school, and tons of costumes and memorabilia on display.
