Movie Revisited

I thought of this movie for the first time in years after seeing James Caan on TV the other night. I was surprised to see that Harrison Ford was in it. And there were still five years to go before his appearance in American Graffiti really got him noticed. I remember when this came out that it didn't get good reviews, but I liked it. I also remember reading that Caan wasn't happy with his role and didn't put much energy into acting. I think he even wore a wig to be less recognizable.
