These shots aren’t new. Not even in the sense they just hit the net. But let’s take a fun trip ‘Back to the Future,’ to the set of 1985. This is when ‘misterbiscuit’ took a job as a security guard at Universal Studios to be on the set of ‘Back to the Future.’

While the first movie was a big hit in 1985, the other two weren’t as big as you would expect. The first made $210 million, the second $118 and the third $88 million. Worldwide they respectively did $380 million, $330 million and $244 million. Still profitable, but I reckon the DVD and VHS sales were responsible for a big part of the third movies’ revenue.

The second row of pictures compares the set of 1985 to the one set in 1955.

As I left you with the last ‘Sex and the City’ box office numbers, I just had to come back with another classic Sarah Jessica Parker photo (1, 2, 3, 4, 5). As you might know by now, ‘Sex’ made $57 million this weekend, beating most expectations. The first number, $27 million last Friday, indicated an even better opening. But the movie was front-loaded, meaning most women went to the TV series follow-up the first day. Still, $57 million is impressive for a budget of just $65 million.

But while the movie was ‘front-loaded,’ it doesn’t mean the theaters are empty by now. ‘Sex’ made another $5.5 million this Monday, showing its potential staying power. It beat the old ‘Indiana Jones 4′ by $2 million. Not bad for a movie that some deemed as ‘just another chick flick.’ Overseas the movie managed to take another $37.5 million. Not bad either, since the movie has yet to launch in over half of its territories. Especially the U.K. was hyped for ‘Sex and the City,’ with $17.3 million at just 460 screens.

Years of TV made this one pink movie no woman can miss out on. Early Tuesday estimates indicate another $5.5 million. These girls will be around for a while.

No, even I didn’t see this one coming. Warner Bros. and New Line Cinema are reporting ‘Sex and the City’ grossed $26.9 million yesterday (Friday). I’ve been very optimistic about Sex’ performance, but I never thought it would have a shot at $70 million for the weekend. Meanwhile, ‘Indiana Jones 4′ is doing a little less than expected, just like we saw in our weekly box office roundup. Spielberg’s oldie took in $12.2 million, meaning it would come in at a little over $40 million for the weekend. But when I said ‘Sex and the City’ could beat Indy, I didn’t think it would actually happen.

The other new release, ‘The Strangers,’ surprised as well. The cheap $10 million thriller made an impressive $7.5 million. Universal must have seen the potential hole it could fill between Sex and Indy. The Liv Tyler vehicle has a shot at $25 million for the weekend.

Lastly, the switch has finally happened. ‘Iron Man’ took $3.7 million, while ‘Prince Caspian’ came no further than $3.4 million. Sorry Disney, your $200 million pet is on its way out.

More numbers as they come in.
