Question: Did Craig Schlattman and Carl Reiner both do great work in front of the camera as well as writing and directing?
Context: Estelle Reiner (June 5, 1914 – October 25, 2008), described by "The New York Times" as "matriarch of one of the leading families in American comedy", was an actress and singer.  She was the wife of Carl Reiner and the mother of Rob Reiner. The Dick Van Dyke Show is an American television sitcom that initially aired on CBS from October 3, 1961 to June 1, 1966, with a total of 158 half-hour episodes spanning over five seasons.  The show was created by Carl Reiner and starred Dick Van Dyke, Rose Marie, Morey Amsterdam, Larry Mathews, and Mary Tyler Moore.  It centered on the work and home life of television comedy writer Rob Petrie (Van Dyke).  The show was produced by Reiner with Bill Persky and Sam Denoff.  The music for the show's theme song was written by Earle Hagen. Document cameras, also known as visual presenters, visualisers (in the United Kingdom), digital overheads, or docucams, are real-time image capture devices for displaying an object to a large audience.  Like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies.  They are, in essence, high resolution web cams, mounted on arms so as to facilitate their placement over a page.  This allows a teacher, lecturer or presenter to write on a sheet of paper or to display a two or three-dimensional object while the audience watches.  Theoretically, all objects can be displayed by a document camera.  Most objects are simply placed under the camera.  The camera takes the picture which in turn produces a live picture using a projector or monitor.  Different types of document camera/visualizer allow great flexibility in terms of placement of objects.  Larger objects, for example, can simply be placed in front of the camera and the camera rotated as necessary,or a ceiling mounted document camera can also be used to allow a larger working area to be used.

Historically, in Europe, rulers were sometimes given the attribute "the Great", as in Alexander the Great, Frederick the Great and Catherine the Great.  Starting with the Roman consul and general Pompey, the Latin equivalent "Magnus" was also used, as in Pompeius Magnus, Albertus Magnus, and Carolus Magnus.  The English language uses the Latin term "magnum opus", (literally "Great work") to describe certain works of art and literature.
