The Association of Cinematograph, Television and Allied Technicians (ACTT) was a trade union in the United Kingdom which existed between 1933 and 1991.

George Elvin was appointed as its first General Secretary the following year, establishing a journal and an employment exchange.

ACTT were highly critical of the film's negative portrayal of trade unionists.
