Screenwriting cousins Jeff
and Gregg Sherman team up to craft this documentary exploring the darker side of the relationship shared between their famous fathers, Robert
and Richard. Back in the 1960s, Robert and Richard Sherman rose to fame penning upbeat songs for such classic children's films as Mary Poppins
and Chitty Chitty Bang Bang
. But the pair's catchy, optimistic ditties masked a contentious brotherly bond -- which ultimately grew so sour that their sons Jeff and Gregg weren't aware of one another despite the fact that they only lived a few blocks apart.
