The actor was honoured with the 2,572nd plaque on the famous Los Angeles sidewalk on Monday (25Jan16), and he was feted by The X-Files creator Chris Carter and comedian Garry Shandling during the unveiling ceremony.

David's The X-Files co-star Gillian was unable to attend the event, so she wrote a joke eulogy and asked for it to be read out in front of her longtime friend.

"He was a nice man," Gillian wrote. "A kind man. Quite smart. He liked avocado and pilates. Actor, writer, friend. He will always be my shining star. May his soul be forgiven and rest in peace."

Speaking after the ceremony David reflected on his career achievements, saying, "It's indescribable, there are so many memories that come back. I came out to Los Angeles in 1988 trying to make enough money to live and work, that was all I was concerned about was can I pay the rent and act... I've been able to have so many great relationships in the business so for me it stands for all those days when I get to collaborate with those people who are smarter and better than me and can teach me so much. They have a little piece of this."

David and Gillian are back on TV this year (16) in a new series of The X-Files.
