Which Star Trek film was the first to feature the Next Generation crew?

Star Trek: Generations was the first film to feature the Next Generation crew. Released in 1994, it served as a transition between the original-cast films and movies centered on Jean-Luc Picard’s Enterprise-D crew.

The film brings Patrick Stewart, Jonathan Frakes, Brent Spiner, LeVar Burton, Michael Dorn, Gates McFadden, and Marina Sirtis from the television series into their first theatrical Star Trek adventure. It also includes a major crossover with William Shatner, James Doohan, and Walter Koenig from the original cast.

The story begins with the launch of the Enterprise-B and later follows Picard as he confronts Dr. Tolian Soran, a scientist seeking access to the extradimensional Nexus. Captain James T. Kirk returns to help Picard stop Soran from destroying a populated planetary system.

First Contact, Insurrection, and Nemesis all feature the Next Generation cast, but they came later. First Contact was the first film devoted entirely to that crew without a main original-series character, which is why it is sometimes mistakenly identified as the first Next Generation movie.
