 Charmian Carr (qv) slipped and injured her ankle while filming  "Sixteen Going On Seventeen." In early editions of the film, the  bandage covering that ankle is visible. When the movie was produced  on DVD, the bandage was taken out digitally. On the movie commentary  of the 40th Anniversary edition, Charmian said that because of this,  some people do not believe her when she says she danced on an  injured ankle.
