Here at entertainment.ie, we like to praise some hidden gems now and again. '13 Going on 30', however, is pretty widely known and beloved, and it deserves every bit of praise it gets.

Hitting cinemas in 2004, '13 Going on 30' is one of the great rewatchable movies of the 2000s.

It's just such a feel-good, fun movie, and Jennifer Garner is perfection as Jenna Garner.

Before he got mad and turned Hulk, Mark Ruffalo played her romantic interest, Matty, and he's a cutie in the movie too.

The pair are reuniting in 'The Adam Project', co-starring Ryan Reynolds (as their son, funnily enough) and we can't wait to see it.

Garner also recently starred in Netflix movie 'Yes Day', playing another role recalling Jenna, which we love to see.
