The 1999 AD movie “Thrill Seekers,” originally titled “The Time Shifters,” was directed by Mario Philip Azzopardi and stars Julian Richings as Murry Trevor, Martin Sheen as Grifasi, Casper Van Dien as Tom Merrick, Catherine Bell as Elizabeth Wintern, Theresa Saldana as Cortez, et al.
On the surface, it is a sci fi movie which plays off of time travel and the paradoxes which come therewith: causing changes in timelines, alternate timelines, etc.
