IMDB style GOOFS:
The c64's light doesn't work
You can't plug a cartridge into a C64 when the C64 is on. It can cause the fuse to blow. (I know this from experience)
No disc drive connected but the guy uses the load"$",8,2 command. As he was running from tape he just needs to press shift and runstop
He's also using some sort of a futuristic basic release, has "T"'s of memory. I suppose the futuristic C64 doesn't have a power light, loads with that command and deals with hot swapping cartridges.
