The Prospect Theatre Company was an English company founded, as Prospect Productions, in 1961. Based at the Arts Theatre, Cambridge from 1964 until 1969, the company, with Toby Robertson as artistic director and Richard Cottrell as associate director, toured both nationally and internationally with a mainly classical repertoire, providing notable appearances of such actors as Ian McKellen and Timothy West. The company became closely associated with the Edinburgh Festival after its first appearance there in 1967. Separating from the Arts Theatre in 1969, the company, renamed The Prospect Theatre Company, survived without a permanent base for the next eight years under the direction of Toby Robertson, mounting productions in which Derek Jacobi and Dorothy Tutin made significant appearances.
