Why is "Superman in film" trending?

Wikipedia Overview

DC Comics' Superman, created by Jerry Siegel and Joe Shuster in June 1938, has featured in various films. The character debuted in cinemas in a series of animated shorts beginning in 1941 and was the protagonist of two movie serials in 1948 and 1950. An independent studio, Lippert Pictures, released the first Superman feature film, Superman and the Mole Men, starring George Reeves, in 1951. In 1973, the film rights to the Superman character were purchased by Ilya Salkind, Alexander Salkind, and Pierre Spengler. After multiple scripts and several years in development, Richard Donner was hired as director, and he shot two films, Superman (1978), and Superman II (1980), at the same time, both starring Christopher Reeve. Donner had filmed 75 percent of Superman II before it was decided to suspend shooting on the first film. The Salkinds fired Donner after Superman was released and commissioned Richard Lester as the director to finish Superman II. Lester returned to direct Superman III (1983). The Salkinds also produced the spin-off Supergirl (1984). They then sold the rights to Cannon Films, which produced the poorly reviewed Superman IV: The Quest for Peace (1987). Ilya Salkind commissioned a fifth Superman script before Warner Bros. acquired the rights in 1993.
