Almost three months after its launch, this Robert De Niro-led biopic will find its way to streaming and hopefully do better than its disappointing box office performance. Per TVLine, The Alto Knights premieres on MAX on Friday, June 6 and will then air on HBO the following day at 8/7c. In addition to De Niro, who stars in a dual role as 1950s warring crime bosses Vito Genovese and Frank Costello, the drama's cast includes Debra Messing, Cosmo Jarvis, Kathrine Narducci, and Michael Rispoli in supporting roles.
