Here, we investigate thin films of SmNiO_3 subjected to different levels of epitaxial strain. We find that the original bulk behavior (T_N\\'eel<T_MI) is strongly affected by applying compressive strain to the films. For small compressive strains, a regime where T_N\\'eel=T_MI is achieved, the paramagnetic insulating phase characteristic of the bulk compound is suppressed and the MIT becomes 1st order.
