[4][5] By 1910, Marion and her son had relocated to Long Beach, California,[6] where she was employed as a physical education teacher at Manual Arts High School in Los Angeles.

[7][9] They performed interpretive dances, bare-armed and sometimes bare-footed, in filmy costumes, with a repertoire based on Egyptian and classical Greek and Roman themes.

[7] That same year, in Arzner’s Get Your Man, Morgan created a tableau featuring her dancers in a wax museum, which Variety called the highlight of the film.

In Manhattan Cocktail, (1928) the couple paired again, with Morgan choreographing the opening prologue with the tale of Ariadne and Theseus,[16] which her dancers had previously performed on stage.

In 1930, the couple moved into a house they named "Armor", giving nod to Mary Pickford and Douglas Fairbank's "Pickfair", which was located on Mountain Oak Drive in the Hollywood Hills.
