Critique
The film Rorret, which Wetzl co-wrote and directed, was described as having "turn[ed] a thriller into a yawner" by the Boston Globe, but was considered "a cinematic shrine to the creepy classics" by the Buffalo News Vincent Canby on New York Times about the film wrote: "The movie can be best appreciated as the work of an obsessed, talented, ultimately very practical film student."
The film "First the Music Then the Word" was shown in several U.S. film festivals. Among others San Diego Film Festival, 2000, Italian Film Festival of Marin County, 1999, N.I.C.E. (New Italian Cinema Events) in 1998 in New York (Quad Cinema) and San Francisco (Kabuki Theater).
