During his years with Francis Thompson, Inc., Hammid went on to be involved with several other early IMAX films. Graeme Ferguson, co-founder of IMAX Corporation (speaking at Francis Thompson’s memorial service in 2004) recalled how he had wanted Hammid and Thompson to make the first commercial Imax films because of their extensive work in earlier large-scale multi-screen films including "To Be Alive!" (which won an Oscar after being shown at the New York World's Fair in 1964), "We Are Young" (on six screens for the Montreal World's Fair/Expo 67 in 1967) and "US" (for San Antonio's Hemisfair in 1969).
