"The Secret of Nikola Tesla"
1980
This film recounts Tesla's (played by Petar Božović) development of the alternating electric current, first under the dictatorial thumb of Thomas Edison (Dennis Patrick), then on his own. Tesla develops a harmonious working relationship with George Westinghouse (Strother Martin), who indulges the inventor his eccentricities and gives him the credit he deserves, something the tyrannical Edison refused to do. Orson Welles appears briefly as J. P. Morgan in this Croatian biopic, originally released as "Tajna Nikole Tesle."
