Under Suspicion (1992)

REVIEW
The title of this old-fashioned murder mystery refers to the predicament of its two leads (Neeson, San Giacomo), who find themselves pointing fingers at each other over the murder of the latter's lover. Neeson stars as a sleazy private eye (circa 1959 England) whose livelihood of faking adulteries for divorce-seekers is cut short when one of his set-ups ends in murder -- with him as a prime suspect. He immediately sets out to prove his innocence by pinning the blame on San Giacomo, who is the sole beneficiary of the murdered man. This innocent-man-wrongly-accused thriller sports a wild ending twist.
