Including Jack Buchanan (Toni Marr / Marini), Dorothy Boyd (Princess Eugenie), Forrester Harvey (Watts), Hayford Hobbs (Delavine), Henry Vibart (Gardo), Moore Marriott (Meyer), Lawson Butt (Mendel), and Frank Goldsmith (Olsen).
Jack Buchanan had played the lead role in the stage version of Toni from its original tour of the English provincial theatre circuits through to its West End debut (which was delayed because of Buchanan's American commitments). Buchanan was the only primary cast member from the original theatrical tour to be included in the film version.
