For her body of work accomplished in an especially long career, she was honored with the Lifetime Achievement Award from both the Filipino Academy of Movie Arts and Sciences and the Gawad Urian.

As a teen, Walter appeared on the Manila bodabil circuit as a chorus girl in the stage shows of Katy de la Cruz.

Walter first came into fame in 1928, when she starred in Ang Lumang Simbahan, staged from the popular novel by Florentino Collantes.

A chain-smoker, her gravelly voice made her ideally cast in villainous roles, most prominently in the 1974 Lino Brocka film Tatlo, Dalawa, Isa.

Contrary to what is published in her IMDb biography, Walter was not the actress engaged in the first kissing scene in Philippine cinema (that distinction belongs to Dimples Cooper).
