Cheating on your spouse heterosexually is so passé. Especially in the movies. But a story about your husband’s other man? Mr. Loverman, a new drama from Britbox starring Lennie James, is about a closeted man who has a 50-year affair with his best friend, unbeknownst to his wife. Until it isn’t. Expect this love story between dapper Afro-Caribbean silver foxes to move you to tears. —Carolina de Armas
