"I'll Be There For You" was not just the name of the Friends theme song -- it was also the cast's mantra.

Jennifer Aniston, Matt LeBlanc, Lisa Kudrow, Courteney Cox and David Schwimmer reunited for a tribute to Friends director, James Burrows, in the NBC special, Must See TV: An All-Star Tribute.

This was one of the first times the actors had all sat down publicly since the show ended in 2004, and they shared memories from their time on set while working with Burrows. "We would do anything for Jim Burrows because he really gave us the opportunity of a lifetime and probably the best 10 years of our acting careers that we will forever remember," Aniston said. "And had some of the greatest creativity."

The 47-year-old actress added, "We experienced friendship, family, heartbreak, babies -- everything together. We also sort of had a wonderful experience with the world loving us as well. They connected with us."

Kudrow also recalled that Burrows gave up his big dressing room so the six stars could play poker together, which was just one of the fun ways the director helped the cast form such a close-knit bond.

"He really encouraged us to get along, get to know one another and be kind to one another, support one another, watch one another and help one another,” LeBlanc explained.

ET caught up with Schwimmer
after he filmed the Friends reunion, and he was quite happy to have had that time with his co-stars. "It was just lovely to all be in the same room," he said. "[Burrows] is a prolific director and he really, really helped forge the cast as an ensemble. He really clarified all those relationships from the get go."
