We have developed a new technique to study superfluidity in saturated liquid-$^{3}\mathrm{He}$ films. Using the enhanced sensitivity of this new method, we directly observe the suppression of the film's transition temperature ${T}_{c}^{F}$ as the film thickness decreases. We also measure a well-defined maximum critical film current which scales with temperature as ${(1\ensuremath{-}\frac{T}{{T}_{c}^{F}})}^{a}$, where $a=1.5\ifmmode\pm\else\textpm\fi{}0.17$.
