For decades now, Bruce Jarchow has been an American actor whose accumulated screen time beats that of most leading names. The first credits arrived long before the title most people know. Drama accounts for the largest share of the work. Work has kept arriving for 46 years, which is its own kind of achievement. The most visible line on the filmography is 'Ghost' (Lyle Furgeson). 'Big' is a second title with real reach.
