Tom Cruise is back in his socks and skivvies -- and re-enacting two of his most infamous roles to promote the 2010 MTV Movie Awards.
Cruise reprises his 1983 role as Joel Goodsen, the tighty-whitey wearing, dancing teen from "Risky Business" -- and this time he's taking direction from Les Grossman, his crass, fast-talking studio exec from "Tropic Thunder".
The MTV Movie Awards air June 6.
