elvis star a a race car driver . his co star be someone who be popular at the time . his character have money trouble . these be the overall quality of viva la vega and and guess what . they be also present in speedway . what make speedway different be the great support cast and bill bixby and william schallert and gale gordon and and lead lady nancy sinatra . the other thing be the chemistry between elvis and bixby and elvis and nancy . elvis and bixby have a real buddy vibe between them and elvis and nancy have a believable chemistry . nancy be an ok actress and but elvis isn not exceptional either . he be a good actor and but he be never go to win any award . it seem like towards the end of his movie career he seem to get a little bored with the same plot and but he turn in a bored free performance here . funny moment include the musical number in the irs office and any scene with gale gordon . gale gordon be one of those comedy legend that probably could have brighten up a tanker of a movie like xanadu . speedway racing sequence be somewhat dizzying . all of the car seem to look the same after a while . but all in all and it be a fun little time filler with goofy moment . the best musical number be the adorable your time hasn not come yet baby and nancy solo number your groovy self be also a highlight .
