Her Greatest Performance is a 1916 British silent crime film directed by Fred Paul and starring Edith Craig, Ellen Terry and Dennis Neilson-Terry.
Gerald Lovelace (Dennis Neilson-Terry) is accused of a crime and wrongly arrested, his mother (Ellen Terry) gives 'her greatest performance' when providing him with an alibi. Joan Morgan plays his daughter.
Presumably this is a lost film.
