He attempted to sue
Aaron Spelling Productions in the early 1990s for not telling him early enough about the mini-series
Dynasty: The Reunion (1991)
(Thomson had starred in the original series
Dinastia (1981) from 1982-1989). In the years following the original "Dynasty," Thomson had become a cast member of the daytime soap
Santa Barbara (1984) and was unable to take time off because of the conflicting schedules. His role on "Dynasty: The Reunion" was recast with actor
Robin Sachs.
