The actors contribute significantly to the success or failure of a series or film. While Kurt Russell played a humorless, depressive and suicidal Jack O'Neil in the 1994 film, Richard Dean Anderson approached things completely differently in the Stargate series. His Jack O'Neill (with 2! L) is bursting with wit and humor, but he also has his serious side.
James Spader credibly and convincingly played the unconventional Daniel Jackson, whose theses are ridiculed by his scientific colleagues. Michael Shanks, who took on the role of Daniel Jackson in the series, not only looked very similar to James Spader, but he also stuck to his model of the character and was convincing in this role.
Both in the film and in the series, Erik Avari embodies the clan leader Kasuf, and Alex Cruz embodies his son Skarra.
Kasuf's daughter Shau'ri / Sha're (Mili Avital / Film - Vaitiare Bandera / Series) and Catherine Langford (Viveca Lindfors / Film - Elizabeth Hoffman / Series) also appear in the film and series.
Not featured in the film are Sam Carter, Janet Fraiser, George Hammond and Teal'c. These characters were not introduced until the series.
