E. Phillips Oppenheim 
The Cinema Murder 

A 1919 American silent drama starring Marion Davies, The Cinema Murder is based on the 1917 book by E. Phillips Oppenheim. Elizabeth Dalston (Davies), who is preparing for a career in theatre, sees what seems to be a murder, as stated in a film magazine. She is horrified and unsure of the specifics, but she maintains strict confidentiality. She meets writer Philip Romilly (Barrie), who prepares her for her first theatre role, on a ship headed back to the United States. Although the killer is also traveling aboard the cruise, there is no real danger. Elizabeth participates in the summoning as the performance begins and is successful. The show's financier Sylvanus Power (Randolf), who is laying claim to Elizabeth's affections, knows that the new star is in love with Philip. Sylvanus then makes the decision to ruin Philip by implicating him in the slaying, only to discover that the allegedly murdered guy is still alive and well. Elizabeth and Philip are together as the movie closes.
