I think the movie starts with a Mars rover type vehicle driving around, then as it moves off ...

alien ships come up out of craters.... or something like that...

I can almost see it... but, can't get past this to what movie it is.. I'm pretty sure it's a comedy..

it's driving me nuts! Can you help with the title? And I know I'll feel so stupid when I get the answer.... getting old sucks...the memory just isn't quite the same. LOL
