sentences:  Lah's "One Droopy Knight" was nominated for the 1957 Academy Award for Best Short Subject (Cartoons).However, for the most part, both the 1955–1957 CinemaScope "Droopy" and "Tom and Jerry" cartoons had lost their appeal in the eyes of critics, due to weaker stories and simplistic animation, brought on as the result of cuts to their budget.To keep the studio alive, MGM had begun reissuing previously released cartoons since the 1940s, but in late 1956 decided that, since the reissued shorts brought in as much revenue as the new shorts, it could save six hundred thousand dollars a year by ending new production.
