The Late Great Dick Randall, who also produced the film, leads an all star cast in this international spy thriller. Dependable Richard Harrison is the womanizing CIA agent (Richard Cannon) who is ably assisted by agent (Huang) played by the diminutive Bruce Le as opposed to the original Bruce Lee. Huang is quite a karate fighter who is in the habit of beating up a legion of bad guys while Richart is scheming on the ladies and only fights when he must. The third member of the CIA team is pretty Sharon Shira (Anna).

They are opposed by the ruthless Viet Cong led by surly Jeong-lee Hwang (Comrade Yang) and (Comrade Asian Girl) played by May Hung with an unfortunate unattractive hair do. The third group is a little less defined with multiple nationality's in the gang although they did through in a Sieg Heil so we would know they are definitely evil. This group is led by (The Boss) Tito Garcia and his partner in crime Dick Randall. Randall's character goes by the name of (Dick) to keep it simple I guess.. They have a fem fatal working for them the exotic (Maria) played by Nadiuska who was fine in the role but was probably better suited for her day job as a Super Model.

Each of these forces were desperate to get their hand on the, you guest it, Secret Formula. Challenge of the Tiger is a solid "B" movie in any language as the plot roles right along with members of all three teams getting, how can we say, neutralized with regularity. The portrayal of violence is perfect with it not being to graphic. A big shout out to Brad Harris who played the Boss's henchman (Leopard) with a lot of menacing intensity. At 47 years old the former great Eurospy star still looked buffed at around 235 lbs or so. Unfortunately, he lost his test of strength to our hero the 115 lbs Huang because Huang knows Karate I guess.

The film would rate a couple of points higher if it stuck to the cute nude scenes, of which they are thankfully many, and dispensed with the simulated sex scenes that almost turned it into a soft core film which bogged it down a bit. The ending could have also been a bit more thought out to tie up a couple of loose ends, but all in all this one's a winner. Thank's Dick.
