however, this movie, made two years later focused on AI run amuck as a central theme

The AI system learned that its mission was to destroy SAM, and it was the preferred option. But when a human issued a no-go order, the AI decided it went against the higher mission of destroying the SAM, so it attacked the operator in simulation.

US military AI drone simulation kills operator before being told it is bad, then takes out control tower (msn.com)

I remember the Forbin Project (1970). The description sounds somewhat like Wargames (1983).

Absolutely! War Games and The Forbin Project are very similar in theme.
