Catherine Weaver is a fictional character in the television series Terminator: The Sarah Connor Chronicles, which aired on Fox from 2008 to 2009. The character, portrayed by singer Shirley Manson, recurs throughout the second and final season, debuting in its premiere episode.
Weaver is a Terminator, a fictional line of androids featured throughout the eponymous franchise. She is identified off-screen as a T-1001. Like the T-1000, she is made of a liquid metal which allows her to shapeshift into other people or objects. These effects were achieved through computer-generated imagery, created by Entity FX.
In the series, the character has taken the place of Catherine Weaver, the co-founder of ZeiraCorp who died some time prior to the season's events. Under her new identity, the Terminator becomes CEO and commences development of an artificial intelligence, later known as John Henry.
The character marked Manson's acting debut. She had grown tired of musical performing and took on acting as a new challenge, though she initially knew little about her character's intentions, and was surprised at how large the role turned out to be. Manson found that portraying a machine was harder than expected, and was initially overwhelmed in her new role, but ultimately enjoyed the experience. Her acting received a mixed reception.
