Excalibur is a 1981 American epic fantasy film directed, produced, and co-written by John Boorman that retells the legend of King Arthur and the knights of the Round Table, based on the 15th-century Arthurian romance "Le Morte d'Arthur" by Thomas Malory.

Project Excalibur
The basic concept behind Excalibur was conceived in the 1970s by George Chapline, Jr. and further developed by Peter L. Hagelstein, both part of Edward Teller's "O-Group" in LLNL. After a successful test in 1980, in 1981 Teller and Lowell Wood began talks with Ronald Reagan about the concept. These talks, combined with strong support from a like-minded group that met at the Heritage Foundation, were a major part of the series of events that ultimately led Reagan to announce the Strategic Defense Initiative (SDI) in 1983. Further underground nuclear tests through the early 1980s suggested progress was being made, and this influenced the 1986 Reykjavík Summit, where Reagan refused to give up the possibility of proof-testing SDI technology with nuclear testing in space.
