This character fancies he's hip
To Vasaria plans a short trip
Meets a Baroness there
But the square doesn't care:
Half-dead air-heads make Mannering flip!
In Frankenstein Meets the Wolf Man (Roy William Neill; 1943), Patric Knowles is the less than scintillating Dr. Mannering; with Ilona Massey as Baroness Elsa Frankenstein, Maria Ouspenskaya as Maleva, and Béla Lugosi as Frankenstein's Monster.
