In 1961, MGM resumed the release of new "Tom and Jerry" shorts, and production moved to Rembrandt Films in Prague, Czechoslovakia (now the Czech Republic) under the supervision of Gene Deitch, who had been hired away from UPA. Although Deitch's "Tom and Jerry" cartoons were considered to be vastly inferior to the earlier Hanna and Barbera shorts, they did receive positive reviews in some quarters. In 1963, the production of "Tom and Jerry" returned to Hollywood under Chuck Jones and his Sib Tower 12 Productions studio (later absorbed by MGM and renamed MGM Animation/Visual Arts). Jones' group also produced its own works, winning an Oscar for "The Dot and the Line" (1965), as well as producing the classic television version of Dr. Seuss's "How the Grinch Stole Christmas!" (1966) featuring the voice of Boris Karloff. "Tom and Jerry" folded in 1967, and the animation department continued with television specials and one feature film, "The Phantom Tollbooth". A revived Metro-Goldwyn-Mayer Animation was in existence from 1993 to 1999.
