What was the name of TV spin off from Sylvester Stallone film

You're likely thinking of "The A-Team", which was a TV show that aired from 1983 to 1987. While not directly a spin-off of a Sylvester Stallone film, it was inspired by his 1982 film "The Expendables".

"The Expendables" film was a direct influence on "The A-Team" with its focus on a group of former soldiers turned mercenaries, and this concept was picked up and developed into the popular TV series.

It's important to note that the film itself was not a spin-off of "The A-Team" but rather shared similar elements of a ragtag group of former soldiers using their skills for good.
