Speedway Junkie is filmed in 4:3 format. Unfortunatelly there are DVDs in 16:9 available, where upper and lower parts of the screen are cut off. So look out for a DVD in 4:3 to enjoy the not crippled film.
Taryn Manning appears uncredited in a car scene with Pez Boy. She has since become known for roles in 8 Mile, Crossroads, Hustle & Flow, TV's Orange Is The New Black and pop duo Boomkat (with brother Kellin).
On TV while Johnny and Eric are at Veronica's is NASA footage, which is public domain (free to use), coming in handy for low-budget film. The voice-over of the footage was Peter Thomas (Forensic Files) bought in at request of the director who liked his work on Nova (1974).
