Witness for the Prosecution (1982)

Efficient, but bitter and stubborn, barrister Sir Wilfred Robarts (Sir Ralph Richardson) returns to his office in London, having recovered from a heart attack. He is subsequently invited to defend Leonard Vole (Beau Bridges), who is the prime suspect in a murder case. Leonard is a former soldier that fought in World War II and is married to his beloved German wife Christine Vole (Dame Diana Rigg). He is unemployed and accused of seducing and murdering the wealthy middle-aged single woman, Emily French, to inherit eighty thousand pounds sterling.
