Every episode of the A-Team had a sequence where the team would
spend their time welding, examining sheet metal and rolling 55 gallon
drums around. This scene was filler to work around the general lack
of content to the plot. This technique extends well past the A-Team,
though, and it isn’t hard to find A-Team sequences in many TV shows
and films once you know what you are looking for. It is a hallmark of
a certain style of bad movie.
