@yyzsantabarbara: Robbie acted in one movie, Carny (1980), in which Jodie Foster and Gary Busey star. Have you seen Robbie’s autobiographical film Once Were Brothers? Very interesting, well worth your time.
Not to minimize Robertson, but Band drummer Levon Helm was in a lot more movies than was Robbie, and Helm’s last two solo albums garnered him a Grammy for each. Levon’s albums draw from his Southern U.S.A. roots (particularly Hillbilly and Blues), while Robbie went in a more modern direction for his solo albums.
By the way, to hear some of Robbie’s best guitar playing, listen to the John Hammond, Jr. album So Many Roads, on which he, Levon, and Band organist Garth Hudson appear. Mike Bloomfield had been hired to play guitar on the sessions, but when he arrived at the studio Robertson was already plugged in. After hearing Robbie play, Mike moved over to piano. ;-) Robbie also plays on Hammond’s I Can Tell album.
It was The Hawks work with Hammond that brought them to the attention of Dylan, who hired them away from John. It wasn't until Music From Big Pink was being readied for release that The Hawks became The Band. At one point in time they were known as Levon & The Hawks. I have a coupla Atco Records 7" 45's from that era, which sold poorly.
