Cindy O'Callaghan (born 18 October 1956) is an Irish-born British former actress.

Bedknobs and Broomsticks is a 1971 British-American musical fantasy film produced by Walt Disney Productions and released by Buena Vista Distribution Company in North America on December 13, 1971.  It is based upon the books "The Magic Bedknob; or, How to Become a Witch in Ten Easy Lessons" (1943) and "Bonfires and Broomsticks" (1945) by English children's author Mary Norton.  The film, which combines live action and animation, stars Angela Lansbury and David Tomlinson.

The plot is set in a fictional Victorian era village in Europe.  Johnny Depp leads the cast as the voice of Victor, while Helena Bonham Carter voices Emily, the titular bride.  "Corpse Bride" is the third stop-motion feature film produced by Burton and the first directed by him (the previous two films, "The Nightmare Before Christmas" and "James and the Giant Peach", were directed by Henry Selick).  This is also the first stop-motion feature from Burton that was distributed by Warner Bros.  Pictures.  It was dedicated to executive producer Joe Ranft, who died during production.

The production is a parody tribute to the science fiction and horror B movies of the 1930s through to the early 1970s.  Along with O'Brien, the film stars Tim Curry, Susan Sarandon, and Barry Bostwick and is narrated by Charles Gray with cast members from the original Royal Court Theatre, Roxy Theatre, and Belasco Theatre productions.
