21GRAMS, part of Real Chemistry, has announced that Nick Mason and Avery McCarthy have formally joined the leadership team of ROOM42, its embedded production company.

Launched in 2024 with the mission statement “We create for creators,” ROOM42 serves as the production arm of 21GRAMS, delivering film and other content across the agency’s global client base. The appointments of Mason and McCarthy reflect the studio’s continued investment in craft and storytelling at the highest level.

Mason and McCarthy share creative leadership of ROOM42, with McCarthy guiding the directing roster, and Mason pairing his own directorial work with oversight of the studio’s post-production craft. Together, they collaborate with agency teams to bring bold ideas to life with emotional storytelling and technical excellence.

The formalisation of this capability follows a period of growing recognition for ROOM42’s work, which has already spanned high-profile campaigns across immunisation, oncology and rare disease. Mason’s own films have been recognised on the international circuit at shows including LIA, Clio Health, Drum, New York Festivals, Brand Film Awards and PRWeek, establishing him as a director able to bring both humanity and visual ambition to complex healthcare topics. 

McCarthy has likewise earned recognition for his directing, with credits at Clio, One Show, and The Creative Floor, including a bronze for 21GRAMS’ first Clio outside of the Health track, a milestone that underscores his growing reputation for impactful and inventive storytelling.

Working in tandem, Mason and McCarthy are shaping ROOM42’s reputation as a hub for directorial craft and innovative content within Real Chemistry, underscoring the agency’s continued investment to raising the bar for creativity in healthcare communications.
