Long careers are rarer than they look, and Pertti Sveholm has become a familiar face who has seen the business change around him more than once. For much of the audience, Pertti Sveholm is Police Detective from 'The Man Without a Past', whatever else the credits say. 'Heavy Trip' is the other credit most often cited. The career opened quietly, the way most long ones do. Very few actors keep finding work for 44 years.
