A guyot (pronounced / É¡ iË Ë j oÊ /), also known as a tablemount, is an isolated underwater volcanic mountain , with a flat top over 200 m (660 ft) below the surface of the sea. The diameters of these flat summits can exceed 10 km (6.2 mi).
The character first appeared in the 1981 film Raiders of the Lost Ark, to be followed by Indiana Jones and the Temple of Doom in 1984, Indiana Jones and the Last Crusade in 1989, The Young Indiana Jones Chronicles from 1992 to 1996, and Indiana Jones and the Kingdom of the Crystal Skull in 2008.
Tom Selleck was Steven Spielberg 's second choice for the role of Indiana Jones. Harrison Ford was his first, but George Lucas objected, since Ford had been in both American Graffiti (1973) and Star Wars (1977). Selleck was not able to take the role because he was committed to Magnum, P.I. (1980).
