Wilder Napalm (1993) From IMDb: Wilder and Wallace Foudroyant are brothers and pyrokinetics. Ever since childhood they've been able to start fires with their minds, but, following a tragedy in which they accidentally killed a man, the brothers have grown up very differently. Wilder (Arliss Howard) has become a regular 9-5 workaday joe, but Wallace (Dennis Quaid) performs his feats with a traveling circus. When the circus comes to Wilder's hometown, Wallace starts coming on strong to Wilder's wife, Vida (Debra Winger), who ironically is a slight pyromaniac.
I'm taking a leap here. It's the first one that came to mind.
